GK
LONG TERM /THURSDAY THROUGH MONDAY/
ISSUED AT 248 AM MDT TUE APR 1 2025
LARGE UPPER TROUGH OVER THE REGION WILL CONTINUE TO PRODUCE COOL AND
UNSETTLED WEATHER THURSDAY INTO FRIDAY. MOST OF THE PRECIPITATION AT
THIS POINT LOOKS RELATIVELY LIGHT. THEN A RIDGE WILL BUILD INTO THE
AREA. THIS SHOULD PRODUCE MOSTLY DRY WEATHER WITH ABOVE NORMAL
TEMPERATURE FOR SUNDAY AND BEYOND. THE ONLY POTENTIAL HICCUP IS THAT
SOME OF THE MODEL SOLUTIONS ARE SHOWING A WEAK SHORTWAVE TROUGH
PASSING THROUGH ON MONDAY WHICH COULD PRODUCE A FEW SHOWERS. AT THIS
POINT THOUGH, THIS SOLUTION IS IN THE MINORITY.
