Soggy Memorial Day Weather

May 26, 2015: The past 3 days have left us feeling a little waterlogged.  Muggy air (meaning plenty of available moisture in the air) and a series of disturbances through the jet stream have produces nearly on and a half inches of rain since Sunday.

1 So where does this leave us for the month of May as a whole?  The weather has been a little soggy, but nothing too far beyond a typical May.


The regular rounds of rain have pulled us a little closer to getting back to average on the year. We now are within 1″ of being on-track for an average amount of precipitation for a calendar year.

Looking ahead to June (which starts next week), a large area of the country from the Rockies to the Deep South should see a wetter-than-average month.


That chance for above average precipitation does extend into Illinois, but not quite to the Stateline. We are in the “equal chances” category, which means we could see either above or below average rainfall.  This usually points toward an average month, which for us means 4.65″ of rain.

Thursday’s Severe Threat

The threat for severe thunderstorms still exists on Thursday.

Before we get there, we see the development of showers and thunderstorms overnight on Wednesday, producing a quarter to a half inch of rainfall. As of right now, these thunderstorms do not look to have the capabilities of turning severe. Same story as we head into early Thursday morning. Scattered showers and possibly thunderstorms can occur. The chance of these posing a severe threat is low, but I DO NOT want to rule out the chance completely.

4-8-15 timing








The Storm Prediction Center has much of Illinois (including the Stateline) under an enhanced risk for severe thunderstorms.

4-8-15 spc convective outlook








We start to see the potential for these to turn severe as we head into the early afternoon. As of right now, it looks like thunderstorms will continue to develop and pose a severe threat between 1PM and 6PM on Thursday.

If these t’storms turn severe, the possible threats include damaging winds, large hail, and isolated tornadoes. Now is the time to start thinking of your safe place at home, work, and school. Please remember, tornado sirens are for outdoor warnings within ear’s reach. A NOAA Weather Radio is a great way to receive weather alerts indoors.

4-8-15 expect









In the hours ahead, key ingredients to producing severe thunderstorms can change quickly. We will continue to analyze new information throughout the day. Chief Meteorologist Alex Kirchner will have the latest on 13 News at 5, 6 and 10 tonight, to let you know if the timing or the threat for these storms changes.
Keep up with us on Facebook at and online at for the latest information.

The Easter ‘Punny’ is Here!

We’ve got an EGGStraordinary forecast in store for the Easter bunny this year! As you SCRAMBLE to find plastic eggs during your early egg hunts, morning temperatures will rise to the middle to upper 40’s. HOPPING into the afternoon, temperatures will SPRING into the low to middle 60’s! HOPfully you like your Easter eggs SUNNY SIDE UP, because we’ll CRACK open the clouds and make way for sunshine. Unfortunately, we won’t have an EASTERly wind, as a high pressure system will funnel in a southwesterly wind throughout the day. To all the CHICKS out there, your HARE may be blowing around so you may want extra hairspray. Winds will be gusting up to 30mph. Don’t worry, it should still be an EGGSHELLent afternoon.









If you’ve had an OEUF of the clear sky, we work in some clouds later Sunday night, with a slight chance for a SPRINKLE.

Have a great Easter, YOLKS!

Unusual March

We’ve been so excited for the temperatures this March, the lack of rain and snow has gone unnoticed.

During the month of March, Rockford usually sees 2.3″ of rain. So far, we’ve seen less than half an inch! On average, we usually see almost 5″ of snow. Cut that in half- that’s as much as we’ve seen so far this month.

march so far

However, we could add to that as we head into the start of next week. We’ve got a chance to see some snow heading into Monday, which would bring us a little closer to that average mark.

Not only have we had very little snow and rain this month, but the precipitation that we’ve gotten, all fell in one day (March 3rd)!

It Rained; It Poured

Scattered showers and thunderstorms pulsed up across northern Illinois and southern Wisconsin on Friday. While not everyone got wet, those who did got soaked! So much rain fell in the Forest City that Flash Flood Warnings were issued. Standing water was everywhere.


A new record was achieved in Rockford. The airport picked up 1.35 inches of rain in about two hours on August 1, 2014. This set the record for maximum daily rainfall. In other words, it has never rained so much on any August 1st since records began in 1906. The old record for maximum daily rainfall was 1.32 inches in 2000.

Rain is a Good Thing

Thanks to the spotty nature of our shower and thunderstorm activity over the last couple of weeks, many of us are looking for some beneficial rainfall. The weather observation site at Chicago Rockford International Airport reported a just few sprinkles the last two days. The last two weeks have been nearly bone dry across the area as well. Our lawns, gardens, and farm fields are thirsty!

June Surplus, July Deficit

June Surplus, July Deficit

Meteorological summer kicked off in a wet fashion. The month of June was the 8th wettest June on record in Rockford with 8.06 inches of rainfall. The first half of July followed suit with 2.44 inches of rain falling through the 15th. The second half of July has been anything but rainy. Just 0.02 inches of rain fell in Rockford from July 16th through July 30th. The month is now in the red for normal rainfall, down 1.35 inches.

Beneficial Rain Not in the Forecast Through the Weekend

Beneficial Rain Not in the Forecast Through the Weekend

Looking ahead through this weekend, we will hang onto the slight chance for a few showers (even a rumble of thunder Friday). Since these isolated showers will not affect every corner of northern Illinois and southern Wisconsin, rainfall totals will be slim unfortunately.

Drying Out a Bit

We are going to get some much needed dry time over the next 60 hours or so! Our weather pattern remains similar to what we’ve experienced for most of the summer. With a jet stream diving out of Canada, a northwest flow pattern will allow numerous weather systems to quickly move through the Stateline area.

Our Weather Pattern

Our Weather Pattern

The good news is that the chance of rain through Thursday night is slim to none. At most, a quick shower or two will dot the sky. Otherwise we will get to enjoy many hours of sunshine and pleasant temperatures. Highs will be in the upper 70s and lows will be in the middle-to-upper 50s through Friday (some may call it a perk of a northwest flow pattern)!

FutureTrack Rainfall through Thursday: Little to None

FutureTrack Rainfall through Thursday: Little to None

Rain has been plentiful over the last several weeks. The month of June is in the record books for the 8th wettest June in Rockford’s climate history, thanks to over 8 inches of rainfall. It rained on 20 out of 30 days during June 2014! The month of July is currently on par for rainfall. It rained on 4 out of 8 days so far this month.

Rainy Meteorological Summer So Far

Rainy Meteorological Summer So Far

We actually had rainfall deficits for March, April and May. The rain so far this summer has more than made up for it. Our yearly precipitation total is almost 19 inches which is slightly above average. Looking ahead, the best chance of rain will come Friday and into this weekend with scattered thunderstorm activity each day.

June Rainfall Surplus

The chance for rain has been in the forecast for a while, and it’s going to stay there through the end of the month! We kicked off June 2014 with some rain and thunderstorm activity. Rainfall for the first week of the month added up to just under an inch. Close to another inch of rain fell in the span of two days during the second week of June.

June 2014 Rainfall (through June 24th)

June 2014 Rainfall (through June 24th)

Rainfall totals began to accelerate during the third week of the month. At Chicago Rockford International Airport, nearly 4 inches of rain fell from June 15th through June 21st. Other parts of our area, particularly south and west of Rockford, picked up as much as 8 to 10 inches of rain that week!

FutureTrack Rainfall Potential

FutureTrack Rainfall Potential

Rainfall is now at a surplus for the month of June. For the year, however, we are below average…..but not by much. Even though we’ll hang onto the chance for rain through the end of June, the heaviest rain looks to stay out of northern Illinois and southern Wisconsin. Long range models are giving us between a quarter and one inch through next Monday.

Heavy Rainfall

A nearly stationary frontal boundary is to blame for the heavy rain and flash flooding that affected a large swath of real estate in northern Illinois. Showers and thunderstorms developed along the front Wednesday evening through Thursday morning. Thunderstorm activity sustained itself over the same area for almost 12 hours!

The result was extremely heavy rain, some hail, and plenty of flooding. The hardest hit areas included much of western and southern Lee County, northern Ogle County, far eastern Whiteside County, Carroll County, and western Jo Daviess County. Creeks and streams have filled up and there is a lot of standing water in area farm fields.

Radar-estimated Rainfall

Radar-estimated Rainfall

Isolated pockets of 4 to 6 inches of rain fell along the Route 72 corridor from near Lanark east to Monroe Center, including Shannon, Forreston, Byron, Stillman Valley and Davis Junction. The Dixon, Sterling and Rock Falls area picked up similar rainfall amounts. Southern Lee County—south of Amboy and Sublette—had radar-estimated rainfall totals greater than 8 inches!

More on the Way?!

More on the Way?!

Looking ahead to Thursday evening and overnight, more heavy rain is an unfortunate possibility across our region. Another couple of inches is not out of the question where heavier thunderstorms persist. -Joe

Healthy Dose of Rain

Thanks to some shower activity Tuesday night and a steady rain that fell between 1am and 10am Wednesday morning, our rain gauges have filled up nicely. Areas along and east of the Rock River picked up over an inch of rain. A few spots in DeKalb and McHenry County soaked up almost two inches! Parts of Carroll, Green, and Jo Daviess County hardly picked up anything.

24-Hour Rainfall Totals (10am Tuesday - 10am Wednesday)

24-Hour Rainfall Totals (10am Tuesday – 10am Wednesday)

At Chicago Rockford International Airport (RFD), rainfall added up to nearly two-tenths of an inch (0.19″) fell Tuesday night. Just over eight-tenths of an inch (0.82″ as of this blog post) fell Wednesday morning.
