Area Forecast Discussion National Weather Service Grand Forks ND 201 PM CDT Tue Aug 2 2022 .SHORT TERM...(This evening through Wednesday night) Issued at 201 PM CDT Tue Aug 2 2022 Thunderstorm chances this evening are still the main forecast challenge. As of mid afternoon, a few weaker storms remained over northwest Minnesota, mainly between Roseau and Blackduck. This activity was moving to the east at about 30 mph, being fed by the low level jet, which will continue to shift eastward through the late afternoon (out of this FA). Temperatures have risen to the mid 70s to mid 80s, with dewpoints in the mid 60s to around 70. The main surface low was tracking into southwest Manitoba, with a trough or dry line extending to its south, just west of a Minot to Bismarck line. The true cold front was located from far southwest Manitoba toward the Williston area. The surface low will push to just north of Winnipeg by 7 pm, with the trough and cold front somewhere over northeast North Dakota. By 1 am tonight, the low should be into southwest Ontario, with the cold front nearly through the entire FA. This will give a window somewhere in the early evening time frame, where severe storms are possible over northeast ND into adjacent areas of northwest Minnesota. Over the past few hours, the various CAMs continue to show several scenarios. Some have the activity in southern Manitoba, some have a few cells in our northern FA, and some show little to no activity. All said, it should be a fairly narrow window, with the storms moving quickly to the east and out of this FA by mid to late evening. Northwest winds will get a bit gusty late tonight into portions of Wednesday. Behind the cold front, Wednesday highs should mainly be in the 70s with dewpoints back into the 50s. .LONG TERM...(Thursday through Tuesday) Issued at 201 PM CDT Tue Aug 2 2022 Overview... The overall pattern for the extended period looks to feature mostly above normal temperatures throughout the remainder of the week becoming cooler for the weekend, along with increasing storm chances from Friday onward. Discussion... Transient upper level ridging is expected to be in place over the northern Plains on Thursday. This, along with winds shifting to a southerly direction, will aid in a rapid warm up to high temperatures back above normal through the end of the week. Subsidence aloft should also yield quiet weather for Thursday. By Friday, there are signals within ensemble guidance indicating that a shortwave will be traveling through zonal flow aloft. At the surface, a low pressure system over the Canadian prairies and attendant cold front look to impact the region Friday. There are still some questions regarding the timing of the wave and any resultant precipitation impacts. Regardless, there is increasing confidence in rain chances, with a conditional threat for thunderstorms dependent upon timing. Ample shear should be present across the northern Plains with an advancing jet streak aloft, but instability will be at a premium, with only a few hundred to 1000 J/kg currently displayed within ensemble guidance. Moving into the weekend and early next week, periodic chances for rain and thunderstorms will remain possible as zonal flow aloft stays in place over the northern Plains. This zonal flow pattern will be induced by upper level ridging over the central and southern Plains. As a result, temperatures look to fall into near normal values during this timeframe. Shower and thunderstorm chances will be tied to any shortwaves that are able to travel through the upper level pattern. Resultant confidence in any one of these waves is low at this time, but the chances will remain possible. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1235 PM CDT Tue Aug 2 2022 Thunderstorms will be the main forecast challenge and would bring the most impacts where they occur. At this point, still believe the main window for strong to severe storms will be in the 6 to 10 pm time frame, and mainly at KTVF and KBJI. Have added thunder to both of these TAFs to cover this potential. Otherwise, expect a cold front to move through tonight, bringing increasing northwest winds for late tonight into Wednesday morning. && .FGF WATCHES/WARNINGS/ADVISORIES... ND...None. MN...None.
