...TRIPLE-DIGIT HEAT FOR PARTS OF THE SOUTH...

...SNOW EXPECTED HIGH IN THE NORTHERN ROCKIES LATER SATURDAY...


THE JET STREAM CONTINUES TO BE DISPLACED FAR TO THE SOUTH OF ITS
SEASONAL NORMAL. AS A RESULT, THE WEATHER ACROSS THE UNITED STATES
WILL BE UNUSUAL IN SEVERAL WAYS FOR THE THIRD WEEK OF AUGUST. THE
PACIFIC NORTHWEST AND NORTHERN UNITED STATES ROCKIES CAN EXPECT A
COLD STORM TO ROLL IN BETWEEN NOW AND THE WEEKEND, TRIGGERING
WIDESPREAD SHOWERS OVER THE LOWER ELEVATIONS AND SNOW HIGH UP IN
THE MOUNTAINS AS THE DAY PROGRESSES SATURDAY.

OVER THE CENTRAL STATES, A COMPLEX PATTERN OF FRONTS WILL FOCUS
BATCHES OF HEAVY SHOWERS AND THUNDERSTORMS INTO THE WEEKEND. TO
THE SOUTH OF THE FRONTS, A LATE SEASON SPELL OF HIGH HEAT IS
ANTICIPATED OVER KANSAS, MISSOURI, ARKANSAS, OKLAHOMA, TEXAS, AND
INTO THE NORTHERN GULF STATES.

ALONG THE EAST COAST, EXPECT UNSETTLED CONDITIONS FROM VIRGINIA
NORTHWARD AS A SERIES OF WEATHER DISTURBANCES SLIDE IN. FARTHER
SOUTH, SOME OF THE HEAT EXPECTED OVER THE MIDWEST SHOULD AFFECT
GEORGIA BEFORE A COLD FRONT SLICES INTO THAT STATE FROM THE
NORTHEAST LATE SATURDAY.
