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)

Off-and-On Rain Chances

Don’t let the 7-Day forecast discourage you! Sure, we have a chance of rain on five of the next seven days. However, we are not expecting all-day rains or a deluge of water. Although our gardens, fields, and yards could probably use a little more water! The soaking rains will stay across parts of the mid-South and southern Mississippi River valley.

FutureTrack Rain: Regional View

A system currently in the southern Plains will lift north into Michigan by midweek. This means we have a chance for rain from now through Thursday. A majority of the daylight hours will be dry today and Tuesday. A very slight chance for a quick shower or two is possible this afternoon.

This Week: Small Rain Chances, Spotty Coverage

Clouds will be on the increase Tuesday, but our rain chances should hold off until late morning. Scattered showers will stay in our forecast Tuesday night through Wednesday. Temperatures will be held below normal during this period.

By Thursday, an approaching cold front will bring the chance for a few afternoon and evening thunderstorms. Much like late Tuesday and Wednesday’s shower activity, coverage will be spotty.

Timing the weekend rain chances

Timing the Rain 90% of us will stay dry on Friday. However, a few sprinkles or light showers could move through our airspace, especially west of Rockford. Temperatures will top out in the lower 80s once again.

Saturday will be pretty nice! Definitely the pick day for the backyard pool or tubing down the river. However, we will need to monitor showers and storms that will move through after dinner Saturday. These will be off and on during the night, lasting through breakfast Sunday morning. Then it’s back to sunshine. However, it will be much cooler on Sunday with 72°, compared to Saturday’s 82°.

A Little Dry

Things are a little dry around here, believe it or not! The latest release by the United States Drought Monitor even classifies parts of Carroll and Whiteside County as “abnormally dry.”

Source: US Drought Monitor, June 5, 2014

Source: US Drought Monitor – June 5, 2014

If the trend continues, more of our area may be added to this category. So far this month, Rockford has picked up just under 0.40 inches of rain. However, we are down nearly 3 inches of rain for the year thanks to a drier than average spring.

Our farm fields, gardens, and lawns could definitely use a little help from the sky! That help may come Saturday and Sunday, although it appears we will not see much more than a few tenths of an inch of rain.

Catching up on Rain

With not much else to talk about on this dreary Wednesday, I figured that we should take a look at rainfall! Heavy rain to the tune of 3 to 6 inches inundated parts of Nebraska, Iowa, Missouri, and central Illinois last night.

Locally, our rainfall totals were much lighter. The heaviest rain—generally between one-third and one-half inch—fell in southern Whiteside, southern Lee, and southern DeKalb County. The highest local rainfall totals I found were observed in Mendota (0.45″), Amboy (0.34″), and Sublette (0.34″). These measurements will likely increase since they were observed at 7am.

Rainfall through 7am Wednesday

Rainfall through 7am Wednesday

We actually need the rain around here! Meteorological spring (March, April, May) saw 6.23″ of precipitation at RFD Airport, just 64% of what we typically receive. For the year, we have a deficit of 2.79″ (not including Wednesday’s rainfall).

Rainfall Deficit nearing 3"

Rainfall Deficit nearing 3″

We’ll catch a break from the rain with a couple of sunny days on Thursday and Friday. The chance for rain and thunder returns this weekend. Check out the 7-Day Forecast!
