044 FXUS63 KFGF 071523 AFDFGF Area Forecast Discussion National Weather Service Grand Forks ND 1023 AM CDT Fri Jun 7 2024 .KEY MESSAGES... - Precipitation chances across the area at various points this weekend and beyond. && .UPDATE... Issued at 1023 AM CDT Fri Jun 7 2024 Refined pop chances a bit into the afternoon/early evening hours, otherwise forecast remains on track. High clouds moving into the north with some light returns on radar. Maybe a few sprinkles reaching the ground in the far NW, but more likely potential into the afternoon as the more robust returns to the NW spread into the DVL basin and northern RRV. Previous Issued at 620 AM CDT Fri Jun 7 2024 Clouds should be entering the western FA shortly. Rain will not show up with them until later this evening. Forecast remains on track. && .DISCUSSION... Issued at 311 AM CDT Fri Jun 7 2024 ...Synopsis... Clear skies currently over the FA this morning, but clouds are visible to the west on satellite, tracking east. An upper level closed low will push into southern Manitoba and Saskatchewan as the weekend continues. While some guidance shows the low being whisked east by upper level flow, most other guidance shows the low sitting in southern Canada for at least a few days. After that, the next week looks like brief ridging then NW/W flow aloft depending on which guidance set you use. ...Precipitation Chances... In regards to rain, the first system is going to begin today and continue into the weekend. Precipitation amounts from this first wave Friday into Saturday look to be <0.25", but the probabilities for >0.25" are 20 - 30% in the area between MN HWY 200 and I-94. Sunday looks to have precipitation chances too, but the chances are only around 20% at most in the area, and QPF amounts look to be less than 0.10". Next chance for rain will be from a shortwave late Monday into Tuesday next week, but again, moisture looks to be lacking with probabilities for >0.25" about 20 - 30% across the whole area. With both these systems, the chances for severe weather are low, and widespread thunderstorm chances are low in guidance with lack of instability. We are entering the season of pop-up thunderstorms though, so some isolated ones on a sunny day cannot be ruled out. Because of the divergence in guidance with regards to the upper level pattern, predictability for showers and thunderstorms goes down and gets washed out to minor chances nearly every day. We will have to see how these chances show themselves in the CAMS. && .AVIATION /12Z TAFS THROUGH 12Z SATURDAY/... Issued at 620 AM CDT Fri Jun 7 2024 VFR conditions through the period, with brief RA in the Friday night period, around 1z for northern sites moving SE after that. Winds will be northerly, before shifting to westerly with the rain. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None. && $$ UPDATE...MJB DISCUSSION...AH AVIATION...AH
