Black Locust Winter, Then Back to Summer

We are in Black Locust winter today, which is a typically cool period in May that occurs with blossoming of the Black Locust & Tuliptrees.

Temperatures are 52-60 over the viewing area as of 2:30 p.m.

Lake breeze front is enhancing the chill & cloudiness, especially in the northern 2/3 of the viewing area with the northwest to north wind.

However, as quickly as we chill behind cold front & lake breeze front, both work back northward.......gradually.

Warm front moving northward will bring cool showers with east winds late tonight & tomorrow morning to midday (this is actually remnants of MAJOR Plains severe weather outbreak this afternoon-evening). 

Lows tonight will level off in the mid to upper 40s, followed by 50s area-wide up to midday tomorrow.

So, as quickly as these low clouds erode, high & mid clouds will increase & thicken, followed by some wet weather as the front lifts back northward. 

50s may be with much of the area for the day, even with the rain tapering.  The warm front may finally make it to our southern counties by late afternoon with 70-72 in the far south, near 59 at Greater Lafayette & steady low to mid 50s north.

Winds will be strong from the east (turning to southeast far south).


11 p.m.-7 a.m.:

8 a.m.-2 p.m.:

South of a Fowler to Frankfort line, temperatures may rise tomorrow night as the warm front gets northward a bit more.  Thing is, Lake Erie front & Lake Michigan lake breeze front may form a solid mass of cold air from northeastern Indiana to northern Illinois, impeding warm front movement northward.

That said, areas north of that line may stay cool at 50-55 tomorrow night with 60s to 70 south.

The remnants of severe weather outbreak from Oklahoma, Kansas & Missouri to Illinois will pass 2-7 a.m. early Wednesday morning.

Along & south of the warm front, a couple/few isolated severe storms are possible, but majority of severe weather looks to stay in Illinois, southwestward through Missouri.

Storms look to weaken with eastward movement as they encounter cooler, more stable air with thinning ribbon of instability in the troposphere that will become completely elevated (layer of unstable air atop a cool, shallow, stable layer nearer to the surface). Also, they will outrun better dynamics & strong low-level jet.

So, isolated severe risk should be confined to Benton, Tippecanoe, western Clinton, Montgomery, Fountain & Warren counties, it appears.

Warm front jets way northward Wednesday with the return of summer!

Winds will be strong from the southwest with highs 83-88 with increasing humidity!

It looks windy & very warm right to early next week with highs in the 80s to 90 & lows in the 60s to 70.

A few storms will flirt with us at times, but the main risk of widespread storms & severe weather risk is next Tuesday or Wednesday.
