Another Round of Scattered Storms

Much like we witnessed on Friday, scattered showers and thunderstorms will dot the radar again on Sunday.  There are some differences in the forecast, however.  With a fast-moving cold front expected to slide through the area early in the day, there will be a limited amount of time for the sun to warm things up before cloudcover and the threat for rain arrives.  Our high temperatures will likely climb into the middle 80s—perhaps only near 80 in southwestern Wisconsin, where the effects of the front will strike first.

A broken line of showers and thunderstorms will develop along and ahead of the front and push southeast through the region.  FutureTrack depicts this potential line of storms entering the Rockford metro around 1pm.  It appears that some areas well west of Rockford could pick up a shower or two before the afternoon hours.  Moisture is more limited with this system, compared to Friday, so not all areas will see rainfall.  Chance of rain is 50%, so some backyards will remain dry on Sunday.

The threat for strong thunderstorms exists.  However, given the swift speed of the cold front, the best chance for any severe weather appears to be just south and southeast of our local area.  Central Illinois and parts of Indiana will have more time to warm up on Sunday, creating an atmosphere primed for a few stronger thunderstorms.  The main threats Sunday will once again be hail and gusty wind.  Excessive rainfall, like we saw on Friday, is less of a threat due to the fast-moving nature of the front and associated thunderstorms.  If your travels take you to Bloomington-Normal, Peoria, Champaign, or Indianapolis, keep an eye on the sky.

Thunderstorms produce overshooting tops in Wisconsin

What’s an overshooting top you say? First, take a look at this visible satellite view from Exactrack|HD just a few minutes ago.

overshooting
I’ve given you a hint where to look with the blue arrows. Intense updrafts from thunderstorms are sometimes able to push air and water out the top of the troposphere (the lowest level of the atmosphere). Because the water isn’t as bouyant at this elevation, it descends back. But just imagine, if it was possible to be at the top of this thunderstorm, the sky wouldn’t be blue…it would be black!

Cool feature that you can see on the satellite at sunset (and sometimes at sunrise, although storms aren’t nearly as strong in the morning). -Eric

Threatrack-2 Friday evening

THREATRACKA very hot and humid airmass will be in place across Northern Illinois and Southern Wisconsin ahead of a fairly strong cold front that will move southeast into our area by evening.

Temperatures will surge into the middle 90s with dewpoints in the lower 70s. Instability ahead of the front will promote thunderstorm development, mainly after 4pm. Storms will have the capability of producing damaging straight line wind and possible large hail. Stay with the Weather Authority as we keep you updated, especially if you have outdoor plans Friday evening. -Eric

Heat & Humidity Sticking Around

The heat and humidity that we’ve been experiencing across the Stateline over the past few days will stick around as we wrap up the month of August.  While Wednesday’s high temperatures were generally in the upper 80s—a handful of degrees cooler than the previous three days—the humidity was high and it felt hotter because of it.

wknd2

This will be the case on Thursday as highs climb back into the upper 80s (reaching 90 for a few areas south of Rockford).  Our heat index, however, will rise into the low-to-mid 90s.  Things will really heat up on Friday as a warm front pushes its way back through the region.  Highs will reach the lower 90s with a heat index approaching 100 degrees.  With a slight increase in moisture in our atmosphere and a frontal boundary draped across central Wisconsin, a few isolated showers and thunderstorms are possible Friday.

Low 90s will continue on Saturday and possibly Sunday (depending upon how quickly another cold front comes through on the first day of September).  While a very slight chance of rain exists on Saturday, a better chance will come on Sunday with the cold front.  Rainfall totals are not very promising.  Models suggest less than half an inch of rainfall over the next five days, with most models giving us far less than that.  Thanks to our weather pattern, most of the moisture will stay well to our north, riding along the jet stream.  Moisture will also be suppressed far to our south along the Gulf Coast, due to the hot and dry ‘dome’ centered across the middle section of the United States.wknd3

After the cold front moves through on Sunday, our airmass will be siginificantly less hot and humid. Labor Day is poised to have below normal temperatures!

The End is in Sight

Our heat wave continues today, though some cloud cover and last night’s cool front have helped keep things a bit less abrasive. CaptureThe 90s will return Fri-Sun, but a big cool down is just on the other side of those 90s. By Tuesday our high temperatures will struggle to make it into the upper 70s! If you are a fan of the heat then soak in these next few days, if not, then just wait them out because it will be cool again in no time. -GregCapture2

We are on day two this late August heat wave, and many signs point to it lasting until the beginning of the new month. Our hot pattern will hang with us until the beginning of next week when a cooler air mass takes over and takes our temperatures back to more tolerable levels. 1Today straight through Monday will be in the 90s with heat index values climbing even higher. If you enjoy the heat and sunshine then soak it in because this could be our last heat wave of 2013. -Greg

Car Safety

We have jumped head first into the hottest week of 2013 after a summer that has been fairly cool to this point. It is important that as this heat looms over us, we remember a few simple things that could save a life. Car safety can never be stressed enough when the dog days of summer roll around, because a car can quickly heat up like an oven. On a day like today when high temperatures could make it into the low to mid 90s, a car can heat up to deadly temperatures in a matter of minutes. Here are a few examples of just how fast the heat can settle in. Always check the back seat before you close the car door! -Greg 123

Staying Safe During the Heat

With high temperatures expected to climb well into 90s as we start a new work week—and heat index values soaring into the 100s by Tuesday—it’s important to take the proper precautions to beat the heat!

Hazy, hot and humid weather is not uncommon in the Stateline.  However, with the spike in temperatures coming so late in the summer season, many area school districts are dismissing students early.  To find out if your local school is on the early dismissal list, click HERE.

If you plan on being outside in the heat, make sure you stay hydrated and drink plenty of water!  When exercising or working outdoors, don’t overdo it.  Take plenty of breaks and look for shade if possible.  Check on your elderly relatives, friends, and neighbors.  Keep an eye on your kids and don’t leave them in the car; temperatures can be 20 degrees hotter in a closed vehicle.  And let’s not forget to keep our pets cool, either!

The heat will stick around beyond Tuesday, with highs topping out a degree or two on either side of 90.  By Labor Day weekend, temperatures and humidity levels will rise once again!
