Area Forecast Discussion National Weather Service Grand Forks ND 937 AM CDT Tue Apr 29 2025
KEY MESSAGES
- The probability for widespread hazardous weather is low thru the next 7 days.
UPDATE
Issued at 937 AM CDT Tue Apr 29 2025
Still a few clouds hanging around the Waskish area but otherwise clear and quiet this morning. Full late April sun has helped temperatures get into the 30s after bottoming out in the upper teens to 20s a few hours ago. So think there will be little issue reaching the 50s this afternoon.
UPDATE Issued at 706 AM CDT Tue Apr 29 2025
Clouds hugging the far eastern fcst area but will be clearing out mid morning. Otherwise skies clear, with some thin cirrus moving into north central ND at 12z. No changes to prev thinking in regards to today.
DISCUSSION
Issued at 308 AM CDT Tue Apr 29 2025
Synopsis
High pressure is over central ND at 08z. North wind 5 to 15 kts over the fcst area....few gusts 20 kts Bemidji-Park Rapids. High pressure will move over the Red River valley at 18z and then eastern fcst area by 00z. As it does winds will become southerly 5-15 kts this aftn in E ND...with 10-20 kts south winds tonight.
Clear sky most of the day, with very dry airmass per BUFKIT soundings expect little to no CU.
High clouds though will increase eastward ahead of next short wave which will move thru southern Canada from southern Alberta thru southern Saskatchewan tonight and into Manitoba Wednesday.
Moisture with this wave later tonight into Wednesday morning is limited in our area and more north of the border with pops more in the slight chc range and qpf zero to 0.02 inch northeast ND thru 18z Wed.
We will see a better chance for showers Wed aftn/eve as a second short wave moves across the Dakotas 00z-06z Thu. Ahead of it is an area of rain showers with increasing moisture as it moves east into west central MN Wed evening where pops increase to likely.
Bit cooler on Thursday with another short wave moving southeast thru the area. Cold air aloft with 500 mb trough over the area will lead to daytime scattered showers.
Then a big warm up starts Friday and peaks on Sunday as upper ridge builds well north into central Canada and moves overhead Sunday. Highs Sunday forecast to reach 80 degrees in many areas, warmest of the year so far.
Early next week will see the ridge breakdown some but how much it breaks down, how much moisture is spread north ahead of an upper trough over the Rockies remains to be seen.
NBM data used thru the 0-7 day fcst period.
