It is two different weather worlds in the area right now with some sunshine & nice weather in the northwest to showers moving back into the south & some patchy drizzle in the heart of the area.
Temperatures vary from 55-64 as of 12:30 p.m. The warmest temperatures are in the far northwest.
It appears that any sunshine today will be confined to our far northwestern areas.
Highs today should run 58-68 with warmest temperatures in the far northwest.
The system is accelerating some so..............
Showers will continue to migrate northward with time today, so count on showers & even a few embedded t'showers increasing with from south to north. Rainfall coverage & intensity should peak early this evening to early tonight. However scattered showers will continue through the overnight hours, then end Friday morning.
Friday should turn mostly sunny by afternoon & after morning lows of 45-52, highs should reach 62-66. Winds wil be strong from the west to west-northwest at 20-35 mph, adding some chill to the air despite the 60s & all of the sunshine.
Some high clouds will begin streaking in from the northwest & west at sunset.
These high thin clouds will be increasing gradually north of a warm front Friday night to Saturday morning. Friday night-Saturday morning lows will still be cold at 37-44. A few patches of frost are possible once again in our northeastern areas.
Clouds will continue to increase & thicken Saturday morning before we are mostly cloudy to cloudy by late morning-midday.
A few isolated showers are possible midday to early afternoon, then scattered showers & t'storms will be on a rapid increase mid-afternoon & beyond. The greatest coverage & concentration of rainfall will be in the northern half of the viewing area.
Warm front will set up near our southern counties, separating 50 from 70s. Note the heavy, accumulating snowfall northwest of us with temperatures around 32 Saturday with several inches of accumulation likely.
Some isolated severe weather risk could develop south of the warm front & just ahead of the cold front from central Illinois to Missouri Saturday late afternoon-evening. At this point, I do not see any severe weather risk for our area.
There will be a big difference in temperature along the warm front Saturday. Note how it is low 30s in far northwestern Illinois, but lower 70s in far northeastern Missouri & upper 60s in far southeastern Iowa.
Here, our highs will vary from 52-67. It will run 52 in the north to a late evening high of 62 at Lafayette to 67 in our far south in the evening.
Front will be south of us Sunday, so it will be cool & windy with skies becoming partly cloudy & highs 57-62 after 39-44 in the morning.
Warm front will move back northward Monday & stall near I-74 with a round of showers & t'storms in the morning & a few lingering into the afternoon.
It will be the same thing Tuesday with a round of rainfall in the morning & then again in the afternoon-evening.
At this point, much of the area looks to stay north of the warm front, containing any severe weather risk largely south of the area. This also keeps us cooler in the 40s & 50s to some 60s. Some 70s may attempt to get into the far southwest or south.
The warm front shows up well at midday Tuesday. Note how it is already mid to upper 70s in far southern Indiana at that point, but only mid 40s in far northern Indiana. It is all-out summer in the South with temperatures already well into the 80s to near 90 at midday. It is all attributed to the position of the warm front & the blocking ridge west of Greenland.
The [west of] Greenland Block is just not allowing the storm systems or warm front to be thrust northward until perhaps Wednesday to Friday period.
Then, warm weather with some severe weather risk could occur.
Near noon time Wednesday, front may be trying to move northward. At that point, it may be 80-82 in far southern Indiana, but the 70s sneaking into our southern counties with 50s in the far north.
It will still be all-out summer from New Jersey to southern Indiana to Arkansas & Texas & east & southward.
We will monitor. This is a tedious forecast of figuring out exactly where the warm front will set up, separating winter & early spring from summer-like weather.
Thursday-Friday period finally shows midday temperatures in the 70s over much of the area. We shall see! Still going with this forecast trend.
Looks like it could be the upper trough & pretty strong low pressure in the Plains that bucks the trend of Greenland blocking, allowing progression of the warm front northward.
This will likely result in severe weather Thursday from Missouri to Oklahoma. We may get in on some of it Thursday evening-night & some perhaps Friday. The worst of it looks to stay west & southwest of our area, however.
From today to next Friday night (May 3-4), a total of 2-5" of rainfall is likely area-wide. At least it will not be all falling at once or in a 24- or even 48-hour period, but stretched out over a week.
Regardless, this will result in further delays in spring field work. I did see a large field today that just had anhydrous ammonia put on it, but given the additional rainfall, it will not be planted in corn for a while.
If we can just push this warm front way north, we could get the strong, warm, humid southerly winds. That wind & 77-81 warmth would help to dry things. Unless this new data changes, the front will not get thrust north of our viewing area for nearly another week!
