Flood Watch into Monday - HRRR Hints at Late Evening T-Storm Threat
June 1, 2014 — 1:15pm
Short-Term Flood Risk: Far Southern Minnesota. NWS Doppler radar at 1:08 PM shows strong storms around I-90, from near Albert Lea to Rochester and La Crosse. The initial outflow boundary from last night's flooding storms has pushed south and east of MSP, but conditions are ripe for more storms by evening.
* Flash Flood Watch extended into Monday afternoon for most of Minnesota. Details from NOAA.
Some PM Sunshine - Setting Stage for Another Outbreak? High-resolution 1 km visible imagery (1 PM) shows clearing over parts of central and western Minnesota. If the sun does come out and stay out for a few hours the atmosphere will become very unstable (again), which may fuel another surge of strong storms this evening and tonight.
HRRR Forecast for 9 PM. NOAA's 3 km. HRRR model shows a possible MCS (meso-convective system) capable of more heavy rain and frequent lightning approaching MSP by late evening. Conditions remain ripe for thunderstorms capable of additional flooding into at least the morning hours Monday, followed by some drying Monday afternoon into Tuesday.

Monday was salve for the soul - yes, we all needed that. Today will be partly-bleak with showery rains and temperatures stuck in the 50s, but don't despair. We warm up later in the week with a few days in the 70s. Not exactly strip-down-to-your-swimsuit weather, but mild enough for most outdoor plans, especially Friday and Saturday. A real warm front (80s) may show up within a couple of weeks. Summer can arrive anytime now...
Well that sure was fun. Fun as a 5-alarm fire, a salad of poison ivy - maybe a tick in your ice-cream sundae? Sorry for those visuals, but the people I bumped into this weekend were NOT AMUSED. But here's the thing. The weather just is. The sky above your head was set in motion by forces beyond our control - beyond our comprehension. We just get in the way...
Well that was fun. A true monsoon rain - typical for October or March, but rare in May, when convection (showers and T-storms) should be the norm. Then again it didn't snow - things can always be worse. A shower or sprinkle is possible today, but no more heavy/soaking rains for awhile. We warm up later in the week - 70s possible by late week, closer to where we should be right now.
It's a little early to panic, but I'm starting to wonder (out loud) if Minnesota will experience a coolish, super-soggy summer. We've been in a blocking (holding) pattern which may break down in the coming weeks. Plenty of sweaty days ahead, in theory. But not this weekend. Today will be perfectly normal, for late March. Have a Plan B. Better weather returns next week; milder and drier.
A few light showers are possible today, especially south of the Twin Cities, but the main event, the third (and last) surge of heavy rain, arrives Saturday. Throw in low, scrappy clouds and temperatures holding in the 40s and low 50s and you have a miserable day, more typical of late March. Sunday looks better with some partial clearing by afternoon as a drying northwest wind kicks in behind the storm. Next week will be better. Not perfect, but better.
