NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
258 AM EST WED FEB 22 2017

VALID 12Z WED FEB 22 2017 - 12Z FRI FEB 24 2017

...MANY DAILY TEMPERATURE RECORDS MAY BE BROKEN FROM THE GREAT
PLAINS INTO THE OHIO VALLEY AND MID-ATLANTIC REGION DUE TO
ANOMALOUS WARMTH...

...HEAVY SNOW IS POSSIBLE ACROSS THE WASATCH AND INTO THE CENTRAL
ROCKIES...

...INCREASINGLY WET CONDITIONS LIKELY FOR THE STATE OF FLORIDA...

A ROBUST UPPER-LEVEL LOW AND ASSOCIATED SURFACE FRONTAL SYSTEM,
TRACKING ACROSS THE EASTERN GULF OF MEXICO AND SOUTHERN FLORIDA,
WILL KEEP SHOWERS AND THUNDERSTORMS IN THE FORECAST FOR PORTIONS
OF THE SOUTHEAST THROUGH THURSDAY. MUCH OF THE STATE OF FLORIDA
COULD SEE ACCUMULATIONS AROUND 1 INCH-- ISOLATED HIGHER AMOUNTS
WILL BE POSSIBLE.

OVER THE NEXT FEW DAYS A BROAD UPPER-LEVEL TROUGH WILL BE IN PLACE
OVER THE WEST WHICH WILL KEEP A COOLER, MORE MOIST AIRMASS OVER
THE REGION. A COLD FRONT EXITING OUT OF THE ROCKIES AND INTO THE
HIGH PLAINS AND UPPER MIDWEST TODAY WILL CONTINUE ON ITS WAY
THROUGH THE CENTRAL U.S. BY THURSDAY THE SPRAWLING BOUNDARY WILL
SPAN FROM THE DESERT SOUTHWEST TO THE GREAT LAKES/NORTHEAST.
WIDESPREAD PRECIPITATION IS FORECAST FROM THE CONTINENTAL DIVIDE
EASTWARD TO THE GREAT LAKES/OHIO VALLEY THROUGH EARLY SATURDAY
MORNING. THE BETTER CHANCE FOR SNOWFALL ACCUMULATIONS WILL BE FROM
THE WASATCH EASTWARD INTO THE CENTRAL ROCKIES WHERE AMOUNTS OF UP
TO 12 TO 18 INCHES ARE POSSIBLE IN THE HIGHEST ELEVATIONS. AMOUNTS
IN THE ADJACENT HIGH PLAINS ARE FORECAST TO BE 4 TO 8 INCHES.
WINTER STORM WATCHES ARE IN EFFECT FROM WYOMING TO WISCONSIN.
WINTER WEATHER ADVISORIES ARE IN EFFECT FOR PORTIONS OF UTAH,
IDAHO AND MONTANA.

ADDITIONALLY, STRONG GUSTY WINDS WILL ACCOMPANY THIS SYSTEM AS IT
CROSSES INTO THE PLAINS. THE INFLUX OF DRIER AIR WILL INCREASE THE
THREAT FOR WILDFIRES. RED FLAG WARNINGS ARE IN EFFECT FOR EASTERN
NEW MEXICO AND COLORADO. CURRENTLY THE SOUTHERN/CENTRAL HIGH
PLAINS ARE AT A CRITICAL RISK FOR SUCH ACTIVITY BASED ON THE
LATEST STORM PREDICTION CENTER FIRE WEATHER OUTLOOK.

MILD TEMPERATURES ARE FORECAST TO CONTINUE THROUGH THE END OF
WEEK. FORECAST TEMPERATURES FROM THE CENTER OF THE COUNTRY
EASTWARD INTO THE UPPER GREAT LAKES/MIDDLE MISSISSIPPI VALLEY ARE
APPROXIMATELY 20 TO 30 DEGREES ABOVE AVERAGE. CONSEQUENTLY, MANY
DAILY TEMPERATURE RECORDS MAY BE REACHED OR EXCEEDED ACROSS THE
REGION.
