SHORT TERM. (This afternoon through Tuesday night) Issued at 326 PM CDT Mon Apr 19 2021

Minimal impacts from flurries/very light snow showers in the Devils Lake Basin thorugh sunset today, and across our CWA during the daytime period Tuesday.

Main upper low remains over Canada with broad troughing extending across the Northern Plains. A weaker wave has been moving though the region within the north-northwest flow aloft and cold pool/steep low level lapse rates have supported CU development. Thicker CU in the west closer to where wave is tracking may still support a few flurries through sunset, but so far there have been no reports in our CWA. Winds remain breezy during the daytime periods, but with good mixing we are seeing gusts 30-35 mph in the RRV and west. Surface high and weaker winds aloft should result in a little less wind on Tuesday.

Another slightly stronger clipper moves through the region Tuesday and there is a better signal for light QPF across our CWA (though actual measurable probabilities are very low on HREF/NBM). Despite above freezing daytime surface temps, wetbulb profiles are cold enough that precip would more than likely fall as snow if it does develop today or Tuesday. Temperatures tonight through Tuesday night remain well below normal, and depending on radiational conditions we could see colder spots drop to the single digits or lower teens. This could be close to daily record lows at a few locations, but is conditional on the amount of clearing.

LONG TERM. (Wednesday through Monday) Issued at 326 PM CDT Mon Apr 19 2021

The long term period begins dry with an upper ridge over southern mb and the Dakotas. There may be related impacts on Thursday as southwest winds increase and temperatures climb into the 60s, setting up a potential fire weather concern. There will also be potential impacts on Friday evening and Sunday evening as systems move through and may bring wintry mixes during evening/nighttime hours.

Friday . An upper wave extending from low pressure over Nunavut will move through the area Friday evening. An associated clipper system Friday morning could bring some afternoon showers that transition to snow during the overnight period. Their is some increased confidence associated with NAEFS anonymously low H500 heights over south central Canada, however no significant moisture signals at this time.

Another upper ridge translates through the region Sunday night before the upper level pattern transitions to southwest flow. This transition will result in the next wave coming from the southwest and an upper plains surface system bringing another chance for a wintry mix to the southern half of the CWA. Other than NAEFS showing a very strong upper jet, still low confidence in the amount of moisture associated with this second wave.

AVIATION. (For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1227 PM CDT Mon Apr 19 2021

CU field is increasing in coverage across eastern ND and northwest MN with ceilings developing in the 4500-6000 FT AGL range (VFR). Expect this to break up with sunset before redeveloping during the daytime period Tuesday. A few flurries can't be ruled out particularly in the KDVL area, but coverage should be low. There may be a better shot of light snow showers/flurries on Tuesday during the day. Northwest winds gusting 20-30kt are also expected to follow diurnal cycle (decreasing with sunset/increasing with sunrise).

FGF WATCHES/WARNINGS/ADVISORIES. ND . None. MN . None.
