ALERT DAY – Flash Flood Watch For Parts Of Area Today & Tonight

Forecast High Tuesday: 68F / Low Tonight: 53F – Last updated Tuesday, October 1, 2019 at 8:55 AM…

ALERT DAY today and tonight… for the potential for heavy rainfall and possible flooding. Please remain extra weather aware, especially if you live in flood prone areas.

FLASH FLOOD WATCH for areas along and south of I-90 through 7:00 a.m. Wednesday. 1″ to 3″+ rain possible. This could cause flash flooding, street/urban flooding, rock/mud slides in hilly terrain and rising water levels on area streams and rivers.

It was sure a steamy, summer-like day to wrap up September. In fact, it was a record-breaker in La Crosse. The high temperature at the airport reached 91F degrees, breaking the old record high of 87F, set in 1996.

A cool front will slowly track east/southeast across the region today and tonight. This front is bumping into an abnormally mild and moist air mass across the region this morning. At the same time, little waves of energy will ride northeast along the front. The result will be periods of showers and t-storms today. I’m not expecting any severe storms, but the stronger storms could produce heavy downpours and perhaps some small hail. We already hit our high for the day right after midnight, when the temp was still around 80F in La Crosse. Expect temps to gradually fall through the 60s today, as winds turn around to the northwest 5-15 mph.

More rain is likely tonight, along with isolated t-storms. With some luck, the heaviest rain may fall a bit farther to our south and east… but this will be highly dependent on where the front sets up. Even so, rain is still likely in our area as well… especially south of I-90. Lows tonight will be cooler, in the low-mid 50s.

The rain should taper Wednesday morning and I think we could see plenty of dry hours during the day. It will be mostly cloudy and cooler though, with highs in the upper 50s to around 60F. Another surge of moisture will bring more showers late in the day and into Wednesday night, but these showers should be lighter than what we’ll see today.

Looking Ahead… Any lingering showers should end early Thursday, then expect partly sunny skies with cool highs in the upper 50s to low 60s. Friday will be a much needed dry day, with partly sunny skies and highs around 60F.

We’ll see another chance of showers and isolated t-storms Saturday with highs near 60F. Sunday looks dry at this point with seasonable highs in the low-mid 60s.

More much needed dry time looks to be in store for next Monday through Wednesday, along with a good amount of sunshine. Temps will be seasonable, with highs in the low-mid 60s and lows in the low-mid 40s.

Try to stay dry today… and have a good Tuesday! -Bill Graul
