KEY MESSAGES

- Strong winds gusting to 55 mph are expected through this evening in the Red River Valley and eastern North Dakota, and a wind advisory remains in effect. Additional strong winds are expected again on Thursday and Friday.

- A Red Flag warning continues through the evening for eastern North Dakota and portions of western Minnesota. Near critical to critical fire weather conditions are again expected over parts of the region each afternoon tomorrow into Saturday.

..Fire weather concerns through the week

RH values have fallen to 30 percent just east of the Red River, and will continue to see humidity drop off in the next few hours before starting to recover. See little reason to make changes to the current Red Flag warning. Tomorrow the winds will be much lower, but still could get some good mixing and RH values down to the 20 to 30 percent range. Will have to watch out for any SPS/HWO needed for near critical messaging. Winds return out of the south Thursday, but dew points will also be rising, so at this point it seems afternoon RH values will stay around 30 to 40 percent. Winds shifting to the west behind the trough axis on Friday will bring drier RHs and strong winds back, so will monitor for future fire headlines.

MVFR ceilings continue to hold on at the MN airports, but should scatter out and go VFR within the next few hours. Other TAF sites are VFR and will remain so throughout the period. Winds are gusting above 35 kts in the Red River Valley and at KDVL, and that will continue through much of the afternoon. Some slight decreases this evening, but there is still a 50 percent chance for gusts above 30 kts for a bit around 00Z. More lowering of winds around 02 to 04Z to less than 15 kts.
