AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK

.DISCUSSION...
AN UPPER LEVEL RIDGE WILL CONTINUE TO DOMINATE IN THE SHORT
TERM...KEEPING TUESDAY AND WEDNESDAY HOT AND FAIRLY DRY. WITH

WILL INCREASE THURSDAY THROUGH SATURDAY...SO WE MAY SEE A FAIRLY
WET 4TH OF JULY. ENOUGH INSTABILITY AND SHEAR WILL BE IN PLACE FOR
A FEW STRONG TO SEVERE STORMS...BUT WIDESPREAD SEVERE WEATHER IS
NOT EXPECTED. THIS COLD FRONT WILL ALSO COOL THINGS OFF A BIT
THROUGH THE WEEKEND...BRINGING HIGHS DOWN INTO THE 80S.

EARLY NEXT WEEK.
