Area Forecast Discussion National Weather Service Duluth MN 1240 AM CDT Sun Apr 21 2024


- Near-critical fire weather concerns are occurring today and are expected Sunday due to low minimum relative humidity and breezy northwest winds.

- A clipper system will bring light rain late Monday through Tuesday. Some light snow could mix in Monday night into Tuesday.

- Additional precipitation chances late next week into weekend.

Issued at 358 PM CDT Sat Apr 20 2024

Clouds are gradually clearing from northwest to southeast this afternoon. All of northeast Minnesota is already cleared out, and northwest Wisconsin should clear by late this afternoon.
Breezy northwest surface winds with gusts around 20 mph to linger this afternoon, then diminish this evening. RH values have dipped into the 25 to 35 percent range, and may dip a little farther this afternoon before recovering this evening.
Even more dry weather is expected on Sunday with similarly breezy winds but deeper mixing in the atmosphere leading to more widespread 20 to 25 percent min RH in much of central MN into the Iron Range, and extending into the Pine Barrens of NW WI.
Near- critical fire weather conditions look likely again on Sunday afternoon. This will also produce a warm day with high temperatures rising into the 50s to around 60.

A potent upper level shortwave moves through the area on Monday through Tuesday, and should bring precipitation chances beginning Monday afternoon, continuing through Monday night before ending on Tuesday. Monday afternoon and evening as the shortwave moves into the area there is some fairly strong warm air advection going on aloft. There are some indications we may get some convective elements with this, but the probability for getting thunder is still relatively low- less than 20 percent, so have left out of the forecast for now, but I suspect we may be adding it in. Monday will also be on the warm side, with highs pushing into the upper 50s to mid 60s for a large portion of the area, with cooler temperatures near Lake Superior. Late Monday night into Tuesday the cold air moves in from the northwest, and we should get some rain/snow mixture on Tuesday.
Am not expecting much for accumulation, perhaps a sloppy dusting on grassy or elevated surfaces. Precipitation chances dry up for Tuesday night, and with clearing skies, I expect a chilly night with overnight lows dropping into the 20s.

A ridge of high pressure will slide across the area on Wednesday and Wednesday night, keeping the weather on the quiet side with mostly sunny skies and highs in the 50s.

An upper low over the Pacific will move onto the CONUS over southern California Wednesday, then moving across the southern states through the rest of the work week. This system should be able to generate our next chance of precipitation.
Unfortunately, there are some significant differences in the operational models and there is a lot of spread in the ensembles, depicting that there will be a trough axis moving across the area but the details are still unclear. We currently have some small pops beginning on Thursday continuing into Friday and Saturday. Thursday should be near to above normal, followed by cooler temperatures Friday and Saturday. For now, it appears there will be enough warm air aloft to be all rain, but would not be surprised to get some conversational snow overnight.

Issued at 1240 AM CDT Sun Apr 21 2024

VFR conditions persist throughout the TAF period. Some development of scattered diurnal cumulus with bases around 6000-7000 ft develop from late morning through the afternoon for most of NE MN and all of NW WI terminals. BRD should remain far enough southwest that cumulus doesn't develop. Calm to light winds overnight pick up again mid to late morning, with northwest wind gusts up to 20 knots at DLH/HIB/HYR, but slightly weaker for INL/BRD. Winds weaken again this evening.

Issued at 358 PM CDT Sat Apr 20 2024

Strong gusty west-southwest winds over the lake will gradually diminish this evening. A Small Craft Advisory remains in effect for the Apostle Islands zones. Extended this until 10 PM as gusts are still fairly strong out at Devils Island, and expect those to slowly diminish during the evening, which should finally allow waves to decrease as well. Sunday and Monday should be fairly quiet on the lake with west to southwest winds Sunday, but then slowly picking up out of the southwest on Monday and Monday night.
