Temperatures as of 9:55 p.m. are 40-48 over the viewing area, depending on who is clear & who is mostly cloudy with area of cloudiness drifting overhead.
This area of cloudiness in our area should diminish for a window of mostly clear skies, followed by clouds overspreading the area early Saturday morning (with some virga or precipitation evaporating before it reaches the ground).
Lows should run in the 30s to near 40. Some patches of frost may briefly develop during clearing as winds go light, mainly in our eastern areas.
Skies should clear quite a bit Saturday afternoon before they cloud up yet again Saturday evening.
Highs Saturday should reach 58-64 with a south-southwest wind at 20-35 mph.
We are fair game for some showers to begin to arrive after 5 p.m.
Looks like two rounds of scattered showers & a few t'storms Saturday night to early Sunday morning.
Lows of 46-51 are likely with south-southeast winds 15-30 mph.
Sunday will feature some clearing & strong south-southwest to south, then south-southeast winds at 20-35 mph.
It will cloud up again later in the day from south to north with highs Sunday at 61-66 for the area.
Rain & t'storms are likely Sunday night. Total rainfall Saturday evening to Sunday night should run 0.80-1.40" (I bumped totals up a bit).
Scattered to numerous severe storms are possible from eastern Indiana & western Ohio southward with wind, tornado & hail risk.
Here, rain & t'storms will be in an area of very strong lift with the rapidly-deepening surface low in the area.
Given the sharp pressure & gP height drops with arrival & passage of storm, an isolated severe storm or two is possible, even without much ML CAPE here. Risk would be mainly isolated severe gust, but brief, weak tornado also cannot be ruled out near the center of the low here.
MARGINAL RISK for severe (isolated severe storms) is up to IN 18 in our area.
A HIGH RISK is possible from northeast Louisiana, southeast Arkansas to Mississippi & possibly to the Alabama line in future SPC outlooks.
It is likely that ENHANCED RISK will be moved northward to southern Indiana (SLIGHT just southeast of here in central & eastern Indiana) & MODERATE extended northeastward to central Tennessee.
If you are prone to aches & pains from low air pressure, Sunday night to Monday morning will be very rough for you.
Surface low will be deepening rapidly over the area & may drop 14 mb over a 9-hour period. It could bottom out in Indiana at 979 mb near Angola & 984 mb center tracking right over Benton & White counties.
Blizzard conditions will be occurring in Wisconsin, while a major severe weather/tornado outbreak will take place from southern Indiana & Ohio to the Gulf Coast.
After much of the rainfall & t'storms, the winds should roar in with the cold air after 6 a.m. Monday.
With such a strong surface low & the Arctic high to our northwest, a damaging high wind event is possible Monday morning-afternoon with northwest gusts 45-60 mph. A few isolated +60 mph gusts are possible.
Model SUSTAINED WINDS (not gusts) are projected at 25-32 mph.
Monday will be a mostly cloudy to cloudy day with some scattered rain/snow to snow in the morning, then perhaps a few flurries & snow showers. 36-44 in the morning should level off around 35-41 in the afternoon.
Monday-Friday look unseasonably cool next week with freezing temperatures at night. Coldest night looks to be Thursday night with 24-28 & widespread frost with clearing skies & light winds.
Some scattered rain/snow & snow showers are possible periodically Monday-Thursday with localized, brief, very minor snowfall accumulation on grassy surface at times.
All days look breezy to windy.
Things should change rapidly after April 19 with much warmer, wetter & stormy weather.
