KEY MESSAGES

- Near critical fire conditions particularly southeastern North Dakota Monday.

- 50% chance for areas to see greater than an inch of rainfall Monday through Wednesday, highest chances across southeastern North Dakota and west central Minnesota.

UPDATE
Issued at 634 PM CDT Sun Apr 14 2024

Increasing high/mid level cloud cover tonight as upper level wave moves along the International border. Radar has shown some weak returns, but airmass sub cloud layer is very dry so will maintain dry fcst this evening. Late tonight into Monday in 850-700 mb level warm advection zone developing into SE ND will keep the chance of showers.

DISCUSSION
Issued at 236 PM CDT Sun Apr 14 2024

Sfc ridging will continue to shift east through the night with winds fading shortly after sunset. The red flag warning currently in effect for the northern valley looks set to expire without a hitch.
A s we move into the overnight and winds switch to the west a developing low level jet at 925/850 mb between the approaching upper low to the south and ridging to our then east will present a belt of 30-40 kts winds in the low levels. This will efficiently transfer to the ground as we begin to mix out in the morning with gusts up to 30 mph through the afternoon. Source region for the air will be from the north so on top of it being breezy it will also be a drying wind presenting another day of near critical fire weather as RH of 25-30% and winds over 20 mph combine. At the same time warm air advection builds in on the north side of the nearing low with that low level jet with increasing mid level moisture from the south. Given cold air advection at 700mb and MUCAPE in the 100-200 j/kg range a few elevated thundershowers are possible through the morning hours before mixing heights climb and dry large low level dewpoint depressions become too much to overcome. The most favored area to see any of these showers will be from Valley City to Fargo corridor and south with a 30% chance for 0.10" or more. Primary forecast problem will be if low level dry air will win out or not resulting in mostly virga until the main wave can arrive Tuesday conquering the dry air and finally allowing the more steady rain chances to begin.

Higher confidence in more widespread rain starting on Tuesday. As the main low propagates into the Central Plains, an inverted trough through the region will enhance rainfall. Transient areas of frontogensis will pivot from southwest to northeast as the system as a whole propagates east with the heaviest rainfall totals tied to the track of these bands. In addition, embedded thunderstorms in conjunction with where the heaviest bands of rain pivot will vary rainfall totals over short distances. Hence why, in this type of setup, the areal coverage of higher totals remains in question.
Where heavier rain can organize, over an inch of rain is likely to fall, outside of these pockets around three quarters of an inch or less of rain is more likely. Probabilities remain at 50% for receiving 1 inch of rain, highest in southeastern North Dakota.
Probabilities for 1 inch fall to 20% across northwestern Minnesota and adjacent parts of North Dakota where there is less confidence in those heavier rain bands. Besides the rain, strong southeasterly winds due to a low level jet east of the inverted trough will produce wind gusts through Tuesday in excess of 40 mph.

As the low propagates east on Wednesday, rainfall will taper from southwest to northeast. During this time the FA falls on the backside of the passing low, which with associated cold air advection will increase northwesterly winds through the day. These winds will continue and pick up as the pressure gradient tightens on Thursday. The trailing low over southern Canada associated with the inverted trough will slowly propagate south. This will provide a low chance (30%) of rain and/or snow showers, especially north of highway 2. Winds will remain elevated into Friday, with cooler temperatures. High temperatures to end the week will be stuck in the 40s, with overnight lows dipping into the 20s.

AVIATION /00Z TAFS THROUGH 00Z TUESDAY/
Issued at 634 PM CDT Sun Apr 14 2024

Increased high/mid clouds into Monday. Northwest winds go light and turn north-northeast overnight and then east-southeast daytime Monday. Winds speeds increase quickly Monday west of the Red river valley with gusts over 25 kts in DVL area after 15z.
