FORECAST DISCUSSION

AFTERNOON – OVERNIGHT: An upper-level trough continues to remain in control of the weather across the region today. This has resulted in an overall, unsettled week and that will not change today.

A few light showers are moving through northern zone 6 and into zone 7. Through the morning into the afternoon scattered showers will start to develop across the eastern portions of zone 6 and 7. By 1-2 pm best chances for rain will remain across eastern Illinois.

2pm

Through the evening we will see another disturbance move into the region from the northwest.

As the upper air disturbance moves in, rain chances will once again increase across zone 7 by 5-6 PM this evening.

6pm

Through 7-8 PM the disturbance will remain in place across Illinois. While the initial surge of rain will be moving into eastern Illinois and western Indiana, continuing isolated to scattered rain showers across zone 7 and perhaps zone 6 will be ongoing. Some of these may mix in with some wintry precipitation as well!

Through the evening into the overnight the disturbance will move off to the areas east. As the sun sets we will also lose any daytime heating. These two factors will allow for precipitation to fade out through the evening hours tonight. By the time 12-1 AM rolls around very few, if any, showers will be in place.

Lows overnight will be chilly across the forecast area with temperatures dropping into the mid 20’s north to mid 30’s south. For that reason, there is a freeze warning in place tonight into Saturday morning for the entire forecast area.

New rainfall totals through early Saturday will be around .10-.20” in areas that see the rain showers today into tonight.

WEEKEND: Late Friday night into Saturday an area of high pressure will move over the forecast area. This will allow for a quiet, but cool start to the weekend.

Saturday does look to be sunny to mostly sunny across the region. However, temperatures will remain on the chilly side with highs only topping out in the upper 30’s north to low 50s south.

Saturday night clouds will start to thicken up as the area of high pressure moves off to the east of the region. Through the early overnight a warm front will start to lift through Illinois. As it does a few isolated showers will be possible along the front. It is possible that with the cold air in place some of the showers will fall as snow or a rain snow mix. Regardless, it doesn’t look like these will be very widespread in coverage.

SUN1AM

Lows Saturday night into Sunday will be in the low 30’s to low 40’s.

Sunday the warm front will lift to the north and northeast through Illinois during the early morning hours. As it does, a surge of low-level moisture will start to be transported in from the south and southwest.

Ahead of the moisture, rain and some storms will start to develop and move into zones 6 and 7 around 8-10 AM Sunday morning.

SUN10AM

By 12-1 PM Rain and some t’storms will spread across both zones.

SUN1PM

 Through Sunday afternoon rain chances will continue across Illinois. While it doesn’t look to be an all-day rain, scattered areas of rain will be in place.

Highs on Sunday will feel more like Spring as temperatures top out in the mid 50’s north to mid 60’s south. Winds will be strong at times with gusts of 35 mph possible.

SUNPANEL

Sunday night a cold front will start to move south into the region. As it does, rain and a few t’storms will develop along the front and move across the zones Sunday night into Monday.

MON4AM

MONDAY: Rain chances and temperatures will be highly dependent on the timing and location of the cold front on Monday.

Right now it looks like the front will slowly advance off to the south and southeast through the daytime hours. Behind the front an area of high pressure will quickly trying to ridge into the region. So while rain and some thunderstorm chances could linger through Monday evening across the southern portions of zone 6, some sunshine could be working in across northern zone 7.

MON5PM

Highs on Monday will be in the mid 50’s north to mid 60’s south.

MONPANEL

NEXT WEEK: Once the front and precipitation move out of the area Monday evening/night a large area of high pressure will take over our weather. This area of high pressure looks to remain in place through most of next week.

This will allow for less rain chances and more sunshine as well. Not to mention temperatures will gradually start to warm by mid to late next week to more Spring-like levels!
