High temperatures so far have run 63-69 over the viewing area as of 11:35 p.m. this evening to tonight with a brief period of wind gusts up to 40 mph from the south.
It continues to be one warm, humid March night. There is a hint of mugginess to the air.
Temperatures as of 11:35 p.m. are running 60-67 with lighter winds, but gusts of +35 mph have been noted in a surge of wind recorded by weather stations just south of area area. Winds tonight should increase & temperatures may rise again to 65-70.
Now to the severe weather discussion...........
Already, there appears to have been perhaps three tornadoes in a track over southern Illinois. One small town in Perry County has at least 15 homes with damage, 4 with major damage. Other structural damage is found farther northeastward from that location to near Ina & then Dahlgren, Illinois. NWS will have final word with surveys expected in the coming day or two.
Storms are found well northwest & also south & southwest of our area.
Two main corridors of higher severe weather risk will exist overnight with a substantial flooding threat as well:
1. Southern Iowa to Northern Missouri to Northwestern Illinois
2. Arkansas to Southwestern Indiana.
These are in the zones of ENHANCED RISK for severe weather.
As for us, we remain in the SLIGHT RISK for severe weather overnight to early Friday morning.
Scattered storms will develop in our viewing area with the SLIGHT RISK for severe in the 1 a.m. to 5 a.m. time frame.
An isolated brief tornado, severe gust or two &/or hail is possible. Locally-heavy downpours are also possible.
Still have a way to get weather information if a warning is issued for your location.
Although the main severe weather corridors are south & northwest of us, still be weather-aware.
After 0.30-0.80" rainfall yesterday, 0.40-1.10" fell over the viewing area today. This has lead to overall 0.80-1.90" totals for the past two days atop already wet soil.
There is considerable ponding & high creeks & streams in the area. Any additional rainfall will add to this.
Also, minor to low-end moderate river flooding will be with us now & then right into next week.
After any storms, clearing trend may result in some sun Friday morning with the warmth.
Once cold front passes with gusty showers, temperatures will plunge with wind shift to the northwest.
Temperatures Friday morning will feel nothing like those later in the day as we go from 60s to 30s & 40s.
A round of 40-50 mph (few isolated +50 mph) gusts are possible with this change occurring tonight-tomorrow morning..
