Forecast Discussion:

EVENING – TONIGHT: High pressure is in control to start the day and that allowed for sunny to mostly sunny skies across zones 6 and 7.

However, through the afternoon and into the evening the high pressure area will move off to the regions southeast and our attention will turn to a low pressure system that will bring rain chances to the forecast overnight.

Clouds will start to thicken up from west to east across zones 6 and 7 late this afternoon and into the evening. Rain will enter western Illinois through the overnight, likely impacting the western portions of the zones around 4-5 AM Thursday morning.

THU5AM

By the time you head out to work Thursday morning around 7-8 AM a pretty concentrated area of rainfall will be in place across Illinois. Some of which will be heavy. Overnight tonight into Thursday morning temperatures will be warm enough to support all rain across the forecast area with only perhaps a little snow mixing in across northeast zone 6 and east zone 7 around 6-8 AM. Lows overnight will be in the mid 30’s north to low 40’s south.

THU8AM

THURSDAY: Rain will continue across the zones through the morning hours. Some of which will be heavy. However, by mid-day we will see rainfall lighten up across western portions of Illinois.

THU12PM

Through the afternoon rain chances will continue across the forecast zones. However, the heaviest rain will be out of the forecast area with only isolated to scattered areas of rainfall persisting.

THU5PM

Highs on Thursday will be in the upper 30’s north to mid 40’s south. Winds will be out of the east at 5-15 mph.

By 7-8 PM most of the rain will be over across the forecast area with only some isolated to scattered light showers sticking around.

Rain looks to come to a complete end just after midnight Thursday night into Friday.

While some areas of heavy rain will be possible, I think most places will get .10-.30” of new rain. However, under the heavier areas of rain some places could see .40-.60” of total accumulated rain.

NAMRAIN

Overnight Thursday into Friday an area of high pressure will build into the forecast region. This will dry us out completely overnight and clouds will be on the decrease late.

Lows will be in the low 20’s north to low 30s south. Keep in mind as temperatures do fall, any wet surfaces in place overnight could become slippery as temperatures drop.

FRIDAY: The area of high pressure will remain in place on Friday. While this will allow for clouds to decrease, especially early on in the day. Overall I will call for a mix of clouds and sun.

FRIPRESS

Highs on Friday will be in the mid 30’s north to upper 40’s south.

As we continue on a northwesterly flow aloft we will watch another area of low pressure ride the flow and impact the area by early Saturday. Lows overnight Friday will be in the low 30’s north to around 40 south.

WEEKEND: By early Saturday morning the area of low pressure looks to be moving to the regions north. While this will bring the chance of some rain showers to zone 7 and possibly zone 6 through the morning hours, this system looks less than stellar and I’m not anticipating much in the way of accumulation.

SAT7AM

Through the afternoon hours Saturday another area of high pressure will start to build in. So we may see some clearing Saturday afternoon/evening across both zones 6/7.

sat4apn

Highs on Saturday will be in the low 40’s north to mid 50’s south.

Sunday an area of high pressure will be in place across the forecast area. This will give us mostly sunny to partly cloudy skies. Although a couple of models show a few showers in western Illinois late in the afternoon and evening, I expect most of the area to see dry conditions through the day.

SUNHIGH

Highs will be in around 50 north to around 60 south.
