EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
1151 AM EDT SAT JUL 26 2014

VALID 12Z TUE JUL 29 2014 - 12Z SAT AUG 02 2014


THE POSITIVE-PHASE PACIFIC-NORTH-AMERICAN PATTERN IS PROGGED TO
REMAIN LOCKED OVER THE CONTINENT FOR AT LEAST THE NEXT WEEK. THERE
IS LITTLE WITH WHICH TO QUIBBLE WITH THE LATEST GUIDANCE AT THE
MEDIUM RANGE, WITH THE LOOPING LONGWAVES DOMINATING THE
SMALLER-SCALE IMPULSES TRAVERSING THE FLOW. WHAT YOU SEE AT DAY 3
SHOULD ESSENTIALLY BE WHAT YOU GET AT DAY 7 ACROSS THE UNITED
STATES--SAVE PERHAPS THE INTERIOR SOUTHWEST, WHERE THE POLAR FRONT
IS EXPECTED TO SLOWLY OOZE THROUGH WEST TEXAS AND NEW MEXICO,
SPREADING COOL, MOIST AIR ACROSS THAT REGION AND ENHANCING THE
MONSOON INTO THE LOWER COLORADO RIVER VALLEY AND SOUTHERN GREAT
BASIN. RAINFALL SHOULD ADD UP CONSIDERABLY TO THE NORTH OF THE
POLAR FRONT OVER THE SOUTH CENTRAL STATES, AS WELL AS OVER THE
GEORGIA AND THE FLORIDA PENINSULA NEAR THE PIVOT POINT OF THE SAME
BOUNDARY THERE. THE CRESCENT FROM THE NORTHERN CENTRAL VALLEY OF
CALIFORNIA TO EASTERN WASHINGTON STILL LOOKS VERY HOT AND DRY,
WITH HIGH-BASED THUNDERSTORMS A FIRE WEATHER CONCERN JUST TO THE
EAST OF THE CRESCENT. THE ENSEMBLE MEANS COVER THE PICTURE
REASONABLY WELL AND SIDESTEP THE MORE GLARING IDIOSYNCRASIES OF
THE DETERMINISTIC SOLUTIONS.
