Storms End By Mid-AM, Warm & Humid Afternoon

High Today: 87F / Low Tonight: 67F – Last updated Tuesday, September 10, 2019, at 8:50 AM…

As advertised, scattered showers and t-storms impacted the region over the past 24 hours, especially Monday evening and into the overnight. Storms are tapering this morning and should shift east of our area by about 10 a.m. Rainfall totals ranged from about .25″ to almost 2.00″ in far southern parts of the viewing area. .97″ fell at the La Crosse airport and about .61″ of that fell from 7:00 to 8:00 this morning as a thunderstorm rolled through.

Otherwise, most of today will be dry with skies becoming partly sunny this afternoon. It will be very warm and humid with highs in the 80s.

A front will tip over and stall just to our south tonight. What I mean by tip over is it will align itself from west to east across the region. This front will likely become active again this evening and into the overnight with scattered showers and t-storms. It will be mild and muggy with lows in the 60s.

That stalled out front will be the focus for additional rounds of showers and t-storms on Wednesday, Wednesday night and Thursday… as disturbances track along the front. Very warm and humid air south of the front will be the fuel to feed these rounds of showers and t-storms. Locally heavy rain will be possible with each complex of storms that develops. As a result, forecast models are hinting at the chance for anywhere from 1″ to 4″ (perhaps locally higher amounts) of rain to fall across the region through Thursday night. This could lead to flooding concerns as the week progresses, so please stay tuned for updates… especially if you have interests along rivers or waterways.

Forecasting high temps Wednesday and Thursday will be tricky due to the rain chances and not knowing exactly where the front will set up. Highs north of the front will be in the 60s and 70s… while temps will climb well into the 80s south of the front. It will remain muggy across the region through Thursday as well.

Looking Ahead… The front should finally sweep through by Friday, allowing for drier, cooler and less humid air to filter in. Highs Friday will be in the low 70s, with rather breezy conditions as well.

Much of Saturday looks dry with seasonable highs in the upper 70s. Slight chance of showers and t-storms Sat. night into Sunday. Highs Sunday will climb into the low 80s.

The latest forecast data continues to advertise warmer temps again next Monday through Wednesday, with highs in the low-mid 80s. Humidity will increase a bit once again as well. Monday looks mainly dry at this point, with small chances for showers/t-storms on Tuesday and Wednesday.

Have a good Tuesday! -Bill Graul
