Weather You Need To Know 6/27/19 with j7409. watch https://youtu.be/g8OHzAr7HDY Scattered thunderstorms capable of very large hail, intense wind gusts and perhaps a couple of tornadoes will be possible across portions of west-central into northeastern Montana Thursday afternoon and night. Other severe storms with damaging wind will be possible from southern Minnesota into a portion of the Great Lakes. Additional strengthening is expected during the next 12 to 24 hours while Alvin remains over SSTs greater than 26 deg C and within a low vertical wind shear regime. By 36 hours, however, the combination of cooling SSTs and a more stable airmass is forecast to induce steady to rapid weakening. Alvin is expected to degenerate into a remnant low by late Saturday, and dissipate by Monday. The NHC intensity forecast is similar to a blend of the consensus models IVCN. HCCA, and FSSE. FORECAST POSITIONS AND MAX WINDS INIT 27/0900Z 15.1N 111.9W 50 KT 60 MPH 12H 27/1800Z 15.9N 113.5W 55 KT 65 MPH 24H 28/0600Z 17.3N 116.0W 55 KT 65 MPH 36H 28/1800Z 18.7N 118.1W 45 KT 50 MPH 48H 29/0600Z 19.6N 119.9W 35 KT 40 MPH 72H 30/0600Z 20.7N 122.7W 20 KT 25 MPH...POST-TROP/REMNT LOW 96H 01/0600Z...DISSIPATED The weather pattern over the next couple of days consists of an upper-level low that will persist over the Pacific Northwest, while a slow-moving frontal boundary at the surface remains stretched across the northern tier of the country. Showers and thunderstorms are expected to form and focus along and near this front. On Thursday, an Enhanced Risk of severe weather is in place for the Northern High Plains, as well as a Slight Risk of excessive rainfall/flash flooding. Severe weather and flash flooding are also possible in the Upper Midwest, where Slight Risks of both hazards are delineated. Widespread rainfall amounts there are expected to be 1 to 2 inches, with locally higher amounts. Severe weather and an isolated flash flood could continue into Friday for the Northern High Plains. The aforementioned upper low will cause unseasonably cold conditions, with high temperatures 15 to 25 degrees below normal in northern California and much of Oregon on Thursday. The highest elevations of the Cascades could even see some snow. Meanwhile, summer heat will prevail from the continental divide eastward, with high temperatures reaching the 90s as far north as the Northern Plains and Upper Midwest by Friday. Elsewhere, the southern tier of the country from the Southern High Plains to the Southeast could see scattered summertime thunderstorms, and a few strong storms containing locally heavy rainfall are possible in the Lower Mississippi and Tennessee Valleys on Thursday. Red Flag Warnings are in effect for parts of the Central Great Basin and Four Corners region, where fire weather conditions are elevated.
