Up and Down Temperatures this Week

Temperatures this week will be up and down thanks to how the jet stream is positioned over the Midwest and Great Lakes.  Winds will be coming in from the Northwest, allowing quick moving low pressure systems to sweep down from Canada.  With each low that passes, southerly winds ahead of the low will bring temperatures up, but northerly winds behind the low will knock temperatures right back down.

Gulf moisture will remain limited so as each storm system moves through, skies will most likely remain dry.  There might be a few light rain showers during the day Friday, but even those look to remain relatively limited at this point.

Even though temperatures will warm up ahead of each passing low, highs will still remain below average in the 40's and 50's.  Average highs should be in the low 60's.  We may begin to see a little more of a warming trend towards the beginning of next - with highs back in the 60's.

New Freeze Warnings in Place - Light Snow Falling to the West

A cold front is moving through northern Illinois and southern Wisconsin Sunday evening and will work to bring temperatures from the upper 40's, down into the low 30's by Monday morning.  A Freeze Warning will go into effect for Stephenson, Jo Daviess and Carroll counties beginning at 3am Monday morning.

Light rain showers have been developing directly behind the front from Wisconsin down through Missouri, but snow has also been mixing in where temperatures have fallen into the low 30's.  Already a light dusting of snow has been observed over Wisconsin and parts of Iowa, and even down in the panhandle of Oklahoma!!  As the cold front continues to move east overnight, cooler air will funnel into the Stateline and this may help to support some light flurries or brief light snow showers for some during the overnight - most likely between 1am and 4am.  Don't worry, though, because accumulating snow is not expected.  Already some of the snow on the backside of the precipitation is beginning to break apart in eastern Iowa as dry air is also moving in.

Any accumulating snow will remain to the north in Wisconsin and back further to the west over Iowa.  If any light snow were to stick in northwest Illinois, it would most likely be on grassy surfaces.  With temperatures falling near freezing by Monday morning, however, there could be some slight spots on elevated surfaces.  Something to keep in mind during the morning commute.

Happy Friday Stateline!
It was definitely a frosty and freezing Friday morning throughout the area. This afternoon we will see mainly cloudy skies and highs warming into the mid 40s. Expect a dry start to the weekend, but then the chance for showers returns Sunday and Monday. Some sun and clouds return for the middle of next week.

Some precipitation is showing up on radar, but we should remain mainly dry today. Cloudy skies will be the story today. A few locations along I-80 that are reporting some snow flakes falling. No accumulations are expected, and much of the Stateline area will not see any flurries.

Can we win at scratch-a-4-cast today?

Some sunshine peaking through for your Saturday, but Sunday and Monday bring back the chance for a shower. So we unfortunately didn't win with the forecast.

Freezing Friday

A Freeze Warning is in effect for the entire Stateline area from 1am to 8/9am Friday morning. It will be important to cover or bring inside any sensitive plants and vegetation because if not they may be killed.

Expect temperatures tonight and into Friday morning to dip down into the lower 30s throughout much of the area, but a few upper 20s cannot be ruled out.

Not only will today be well below average, but we will keep the cool weather around Friday and Friday evening. Highs on Friday should top out in the mid to upper 40s, and lows should bottom out in the lower 30s.

Major River Flooding Continues

Significant flooding continues along the Rock and Pecatonica Rivers, with most points at the higher end of moderate flood stage.  The rivers are expected to crest in moderate flood stage, with the exception of the Pecatonica River at Shirland, which is nearing major flood stage, by late this week or weekend.

Here are where the current water levels are at, and when they are expected to crest:

Freeport: 15.29ft  - Moderate Flood Stage
Crest: 15.5ft - Friday Moderate Flood Stage

15.25ft - Moderate Flood Stage
Crest: 15.5ft - Friday Major Flood Stage

Rockton: 12.31ft - Moderate Flood Stage
Crest: 13.1ft - Friday Moderate Flood Stage

Latham Park: 12.76ft - Moderate Flood Stage
Crest: 13.3ft - Friday Moderate Flood Stage

Byron: 14.28ft - Moderate Flood Stage
Crest: 14.7ft - Friday - Moderate Flood Stage

Dixon:  15.8ft - Action Flood Stage
Crest: 16ft - Saturday Minor Flood Stage

Even as the rivers crest into the weekend they will still remain in moderate flood stage through next week. 

Tumbling Temperatures Wednesday Night

The rain showers have come to an end Wednesday evening, leaving us with mostly cloudy skies.  Temperatures Wednesday warmed into the low 70's but are now quickly dropping into the 50's near the Mississippi River.

West winds will increase, gusting to 35mph, behind the cold front that is now passing through southern Wisconsin and northern Illinois. 
Temperatures will continue their fall through the 60's and 50's before falling to 40 degrees by Thursday morning.  But as the winds continue into Thursday, wind chills by morning (yes, wind chills) will make it feel more like the low 30's!  Highs on Friday will only warm to 50 degrees, despite a little more sunshine during the afternoon.

Wet Wednesday - Some Sunshine Tomorrow - Hurricane Michael Update

A wet Wednesday is in store today with showers and thunderstorms,  as a cold front is moving through the Stateline area. Flood Warnings are still in effect for the Rock and Pec. rivers, so be sure to monitor flood prone locations.


Behind the cold front, expect windy conditions and a cool down. In front of the cold front, temperatures are in the 70s and 80s. Behind the cold front, temperatures are in the 40s and 50s.

So sing it with me "so long, farewell..."
Goodbye to the 80s...

And hello to the 40s and 50s!
As we will be "stuck in colder weather" for the rest of the 7 day forecast.

Last night was the drawing for the 6th largest Mega Millions jackpot ($470 million). I only won $2, so let's see if we can win some sunshine on scratch-a-4cast.

We have to match three sunny days in a row, and the next three days we will see some sunshine. It will be a well needed dry stretch.

 Hurricane Michael has officially made landfall just NW of Mexico Beach as a strong Cat. 4 storm. This makes it the strongest hurricane to make landfall along the Panhandle of Florida in recorded history.

Not only will heavy rain and damaging winds be a major concern, but the biggest concern along the coast will be the storm surge. Projections are for 6" + of storm surge.
The cold front moving through our neck of the woods will also help to push Hurricane Michael back out into the Atlantic Ocean very quickly.
