Area forecast discussion, Jul 15, 2:33 PM CDT, 1 hour 3 minutes before
Area Forecast Discussion National Weather Service Grand Forks ND 233 PM CDT Thu Jul 15 2021 .SHORT TERM...(This evening through Friday night) Issued at 226 PM CDT Thu Jul 15 2021 Decreasing impacts are expected tonight as southwesterly winds increase and help scour out the low-level smoke across eastern ND and west central MN. A few weak cells may develop west of the valley this afternoon but will be short-lived and erode after sunset. High pressure now over the top of Lake Superior is resulting in increasing return flow into central ND. The increase in WAA is resulting in widely isold showers/possible a clap of thunder from the upper James Valley into the northern Red River Valley, where MLCAPE values are around 500 to 750 J/Kg. Shear values continue to remain nil so any cells that develop will be rather slow moving and short lived. More likely to see some spits of rain with this activity, although some small hail with the strongest storms is possible. The SW winds are improving visibilities across eastern ND and smoke smell is not as noticeable, however some reports or irritated eyes remain. Will keep FU in on the east side of the river where winds will be lighter and persist through mid-morning Friday. South winds increase more in velocity tomorrow, resulting in highs in the upper 80s and lower 90s. There is potential for elevated smoke from fires over the PAC NW to move into eastern ND late in the period, which could impact afternoon highs. This episode should not be as noticeable at the surface. Overall, a dry and breezy next couple of days as a hotter airmass returns to the area. .LONG TERM...(Saturday through Thursday) Issued at 226 PM CDT Thu Jul 15 2021 Overall dry and warm conditions are expected across the region in the extended time frame. Ensemble guidance brings the strong upper ridge to the area this weekend and through the first part of the week with the heat wave having a high confidence of occurrence. Short term impacts will primarily be tied to above normal summer temperatures with highs in the mid to upper 90s most likely with some guidance suggesting triple digits are possible on the warmest days of Tuesday and Wednesday when the thermal ridge axis settles over the area. Long term impacts would be to enhance the ongoing drought conditions and deteriorating crop conditions. As the upper ridge weakens, weak short wave activity and weak surface wind shifts or boundaries will eventually bring the chance for thunderstorms by Tuesday night or Wednesday to the northern half of the area. This will bring cooler temps however still above normal temps to the area. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 1235 PM CDT Thu Jul 15 2021 Increasing SW winds will help improve vsbys related to smoke for the remainder of the afternoon. Otherwise, mostly clear skies with exception of TVF/BJI seeing remnants of earlier convective activity...those clouds should thin out/move east by end of first six hour period. && .FGF WATCHES/WARNINGS/ADVISORIES...
