DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1244 PM CDT SUN JUL 24 2016

VALID 251200Z - 261200Z

...NO CRITICAL AREAS...

...PORTIONS OF THE CENTRAL/NORTHERN ROCKIES...
A FEW DRY LIGHTNING STRIKES WILL BE POSSIBLE ACROSS SOUTHWESTERN WY
AND NORTHEASTERN UT...AS WELL AS SOUTHWESTERN MT. BOTH LOCATIONS
WILL BE ON THE FRINGE OF GREATER MID-LEVEL MOISTURE...WITH PW VALUES
AROUND 0.5-0.6 INCHES. THE INFLUENCE OF SUBTLE SHORTWAVE TROUGHS
EMBEDDED IN WESTERLY FLOW...COMBINED WITH OROGRAPHIC
CIRCULATIONS...MAY LEAD TO ISOLATED THUNDERSTORM DEVELOPMENT BY
AFTERNOON. CLOUD-LAYER WINDS WILL NOT BE PARTICULARLY STRONG
/ESPECIALLY ACROSS SW WY AND NE UT/...SUPPORTING ONLY MODEST STORM
MOTIONS. WHILE RECEPTIVE FUELS SHOULD ENCOURAGE SOME
DRY-THUNDERSTORM THREAT...A LACK OF STRONGER FORCING FOR ASCENT AND
MORE PRONOUNCED MID-LEVEL BUOYANCY ARE EXPECTED TO KEEP COVERAGE LOW
ENOUGH TO PRECLUDE AN ISOLATED DRY-THUNDERSTORM AREA AT PRESENT.

...SYNOPSIS...
A MID-/UPPER-LEVEL TROUGH WILL DEAMPLIFY AS IT MOVES ACROSS THE
NORTHEAST UNITED STATES. AS THIS OCCURS...A SURFACE COLD FRONT
/STRETCHING FROM THE LOWER GREAT LAKES TO THE MID-MISSISSIPPI
VALLEY/ WILL MOVE SLOWLY MOVE SOUTH AND EAST AND WEAKEN. ACROSS THE
SOUTH AND WEST UNITED STATES....A LARGE...BROAD...AND PERSISTENT
SUB-TROPICAL RIDGE WILL BE CENTERED NEAR THE FOUR-CORNERS AREA.

DESPITE HOT AND DRY CONDITIONS ACROSS THE WEST...THE ABSENCE OF ANY
LARGE-SCALE TROUGHS/CYCLONES SHOULD PRECLUDE THE DEVELOPMENT OF
STRONG PRESSURE GRADIENTS. IN TURN...THE LACK OF ANY LARGE-SCALE
PRESSURE GRADIENTS WILL PREVENT STRONG/GUSTY LOW-LEVEL WINDS FROM
DEVELOPING ACROSS THE AREA...WITH ANY EXCEPTIONS BEING LIMITED TO
LOCALLY DRIVEN OR TERRAIN-FAVORED AREAS. AS SUCH...LARGE-SCALE FIRE
WEATHER CONCERNS ARE LOW.
