StormTeam 8 Forecast: High 80° / Low 62°... Rain shifts east this morning with just isolated showers possible this afternoon & early evening. Otherwise more clouds than sun today. Areas of fog possible late tonight.
Updated Saturday, August 30, 2014 at 10:40 AM...
As expected, several rounds of showers and t-storms hit the region over the past 48 hours... and some of it was quite heavy. Rainfall totals across the region over the past 2 days range from about .50" to 3.50"... including 1.49" at the La Crosse airport. The heaviest rain fell in a band north & west of La Crosse. Hart, MN (Winona County) picked up 3.42" of rain. However, another heavier band occurred south/east where 2.72" fell in Elroy, WI and 2.61" fell near Sparta.
The widespread showers from this morning have pushed east as an area of low pressure slowly moves away from the region. There could still be a few isolated wrap-around showers this afternoon or early evening, but the chance is only around 20%. Otherwise expect more clouds than sun today with highs in the mid 70s to low 80s.
Skies will become partly cloudy overnight and winds will be light. These factors, combined with all of our recent rain, will be good ingredients for areas of fog to develop late tonight into Sunday morning. Expect lows tonight in the low 60s.
Sunday will be warm and fairly humid with highs in the mid 80s. Some areas will see some fog to start, then sunny to partly cloudy skies. A cool front will approach from the west late Sunday and spark another round of showers and t-storms Sunday night into Labor Day Monday morning. Just like a week ago (Sunday night/Monday morning)... some of these storms have the potential of being strong to isolated severe. Strong winds would likely be the main threat. Heavy rain will also be possible.
Storms will most likely linger into Labor Day, especially through about midday. Hopefully we'll get some dry time during the afternoon with highs around 80º.
Looking Ahead... Many area kids head back to school on Tuesday and Mother Nature looks like she's going to provide a dry and pleasant day with highs in the mid-upper 70s. Just a small chance of rain crops up Wednesday, with warmer highs in the low 80s.
A frontal boundary then looks to get hung up across the region Thursday through Saturday, causing another unsettled and potentially stormy/wet period. There could be periodic rounds of showers and t-storms as warm and moist air will be near the region with highs Thursday and Friday in the low-mid 80s. Temps cool into the 70s the following weekend with Sunday looking mainly dry.
Have a safe holiday weekend and be prepared for another round of storms Sunday night into Monday morning. -Bill Graul
