..SYNOPSIS
SLOW MOVING H5 UPPER LOW CONTINUES TO MOVE TO THE EAST AND
SOUTHEAST ACROSS SOUTHERN MANITOBA THIS AFTERNOON. SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS WILL BE POSSIBLE ALONG THE
INTERNATIONAL BORDER AND AREAS SOUTH TO ABOUT HIGHWAY 2. A FEW
STRONGER STORMS COULD FORM THIS AFTERNOON IN NORTHWEST
MINNESOTA. HEADING INTO WEDNESDAY, SHOWERS AND STORMS END DURING
THE EARLY MORNING, WITH DRY WEATHER THE REMAINDER OF THE DAY.
TEMPERATURES WILL BE VERY SIMILAR EACH DAY THROUGH THE WEEKEND,
WITH WIDESPREAD 70S TO LOW 80S FOR HIGH TEMPS EACH AFTERNOON.
OUR NEXT CHANCE FOR PRECIPITATION WILL BE LATE FRIDAY THROUGH
THE WEEKEND AS ANOTHER H5 SHORTWAVE MOVES SLOWLY ACROSS THE
NORTHERN PLAINS.
..ISOLATED SEVERE THUNDERSTORMS THIS EVENING
SHOWERS AND THUNDERSTORMS ARE MOVING ACROSS NORTHWEST MINNESOTA
THIS AFTERNOON, MOST BEING VERY LIGHT. THIS IS IN RESPONSE TO
AN UPPER LOW AND H5 TROUGH EXTENDING INTO NORTHWEST MINNESOTA,
IN THE PRESENCE OF MODEST INSTABILITY AND PEAK DAYTIME HEATING.
AT THIS TIME, THE BEST FORCING REMAINS EAST OF THE AREA;
HOWEVER, THERE IS JUST ENOUGH FORCING, ALONG SMALL LOBES OF
HIGHER VORTICITY THAT ARE MOVING ALONG THE FLOW TO THE SOUTH OF
THE MAIN H5 LOW, TO ALLOW A MENTION OF ISOLATED STRONG TO SEVERE
STORMS THIS AFTERNOON. BEST CHANCES WILL EXTEND SOUTHWARD ALONG
AND EAST OF A LINE FROM LAKE OF THE WOODS TO ABOUT WADENA, MN.
THE PRIMARY CONCERN WILL BE HAIL UP TO 1 INCH IN DIAMETER, WITH
A LOWER CHANCE FOR DAMAGING WIND GUSTS UP TO 60 MPH.
