Major Tornado Outbreak West of Here Saturday……Tonight-Monday Rain/Storm TimingApril 13th, 2012 at 3:00 pm by Chad Evans under Chad's WLFI Weather Blog
SEVERE PLACEMENT TONIGHT-MONDAY…….
Some tornadoes & large hail are possible in Kansas & Oklahoma this evening-tonight. However, the main event will be tomorrow to our west…….
There is a risk of large, violent, long-track tornadoes in eastern Nebraska to Iowa southwestward to Kansas & Oklahoma Saturday. Hail to grapefruit size & downburst winds to 100 mph will occur in some of the storms, as well. Models depict a near-perfect set-up for violent tornadoes………..only missing ingredient is more cold air aloft, but everything else lines up with past violent Plains outbreaks. A few severe storms may get going in western & central Illinois late Saturday afternoon & evening, but I am not too concerned for us at this time.
Severe weather Sunday will stay to our west from Iowa to Louisiana & I am still not concerned about a severe threat here. However, we will watch this.
Severe threat Monday looks to be Kentucky southward.
EVENING TO OVERNIGHT & SATURDAY…….
A few showers are possible by this evening (20-25% coverage, not a big deal), followed by a break.
Overnight, showers & t’storms will develop. These will multiply & congeal into a pretty solid mass of rain & t’storms. This mass will pass in the 7 a.m. to 12 p.m. time frame Saturday, with a migration of the rainfall northeast & eastward afternoon Saturday. Coverage will peak at 100% by Saturday mid-morning.
Some sun may even start to appear afternoon Saturday with windy & warm conditions (highs 69-75). However, an additional wave of scattered showers & t’storms may pass by Saturday evening. Coverage will run at 40%. This looks to be followed by a break Saturday night with lows only in the lower 60s.
PURDUE FOOTBALL GAME & 5K CHALLENGE AT WEST LAFAYETTE…….
The Purdue spring football game looks to be in better shape than the 5K. There will be thunder & lightning around with the 5K WITH the rainfall 7 a.m. to noon. The football game will have the windy, warm, humid conditions with 70s & some sun peeking through. However, late in the day, a few more showers & storms are possible. At least there will be a window there, but that window will be afternoon.
Sunday looks partly cloudy, windy, warm & humid with highs of 75-79. A wave of scattered showers & t’storms is possible late Sunday afternoon-evening with 40% coverage. A break is likely Sunday night with lows only in the lower 60s.
A band of showers & t’storms will pass Monday morning (80%), followed by a break. A narrow, broken line of showers & t’storms is possible on the actual cold front as it passes in the afternoon (35%).
Tuesday looks windy & cooler with partly cloudy skies & highs of 58-63.
FROST STILL LIKELY NEAR APRIL 22 WITH VERY WARM WEATHER BY AROUND APRIL 28…….
After a brief warm-up to 70s to end next week & go into early next weekend, a brief, sharp cool-down with lows of 30-32 appears likely near April 22.
By around April 28, we could see high temperatures of 83-87 with overnight lows of 64-68. It will feel more like June as we end April!
