SLIGHT Severe Threat (2 out of 5) PM Monday
According to NOAA's Strom Prediction Center, there is a SLIGHT RISK of severe storms (2 out of 5 on the severe scale) PM Monday.
Here's more info from NOAA's SPC:
"Weak height falls will occur across the region late today owing to the influence of an eastward-moving shortwave trough crossing the Canadian prairies. A cold front will spread southeastward across the region and roughly bisect Minnesota in a northeast/southwest orientation by around early evening (00Z). A stout elevated mixed layer will exist atop modest early springtime moisture, with surface dewpoints within the warm sector to generally be no higher than the lower 50s around peak heating/mixing. Regional 12Z soundings sampled this limited moisture, with a relative regional maximum noted with the 12Z Topeka sounding sampling around a 9 g/kg mean-mixing ratio and a 9C dewpoint just below 850 mb. Given the modest moisture and the degree of capping, it remains a bit uncertain about the likelihood/coverage of storms across parts of the current categorical Slight Risk. However, at least isolated deep convective development is plausible late this afternoon and especially early evening, particularly across central Minnesota in vicinity of a surface triple point. While initially weak, mid-level winds should strengthen by early/mid-evening and contribute to upwards of 30-40 kt effective shear. Where storms do form, this could support a few semi-high-based supercells aside from multicellular clusters. A combination of severe hail and wind are expected to be the primary hazards as storms spread eastward this evening. A cluster of slightly elevated strong/locally severe storms could persist into the overnight across western/northern Wisconsin and possibly Upper Michigan."
SLIGHT Severe Threat PM Monday
Here is the HRRR simulated radar from around 1PM Monday to 1AM Thursday. According to this weather model, a line showers and storms will develop late Monday across western Minnesota and move into central/eastern Minnesota into the evening and overnight time frame. The main concern with these particular storms would be isolated large hail and damaging wind events, but the severe threat will be fairly minimal.
Soggy Week Ahead
The first full week of April will be quite soggy as a large area of low pressure slowly moves through the region. The weather outlook from AM Saturday to AM Sunday shows the storm slowly swirling through the region with the heaviest rains pushing through PM Tuesday - Wednesday and into Thursday. Light showers could linger into through Friday, but the weekend ahead looks mostly dry and with more sunshine.
Soggy Week Ahead
According to NOAA's Weather Prediction Center, the precipitation potential through the week ahead could feature some 1" to 2" rainfall tallies or more. Some of the heaviest tallies could approach 3" if and where any thunderstorms develop.
Record Warmth on Monday
Prior to our soggy first full week of April 2021, high temps on Monday will be VERY with temps across much of the region warming to well above average levels. There could even be record high temps in a few spots, including in the Twin Cities. Note that the record high in the Twin Cities for April 5th is 80F, which was sent in 1991.
Average First 80F at MSP Airport
Our average first 80F high in the Twin Cities (over the last 30 years) typically happens on April 29th. The earliest 80F high temp was on St. Patrick's Day (March 17th) in 2012.
Monday Weather Outlook For Minneapolis
Here's a closer look at our weather conditions for Minneapolis on Monday. Temps will warm quickly to near 70F by midday with highs approaching 80F by the afternoon. Clouds will increase through the day with a chance of showers and storms late afternoon through the
