...SNOW SHOWERS LIKELY ACROSS PARTS OF THE NORTHERN ROCKIES AND
NORTHERN/CENTRAL PLAINS TODAY...
...MUCH ABOVE AVERAGE TEMPERATURES CONTINUE FOR THE CENTRAL AND
EASTERN U.S TODAY; COOLING TREND SPREADS FROM WEST TO EAST THIS
WEEK....
...CRITICAL FIRE WEATHER EXPECTED FOR PORTIONS OF THE SOUTHERN
HIGH PLAINS TODAY...
A SURFACE LOW PRESSURE SYSTEM EJECTING OUT OF THE ROCKIES INTO THE
PLAINS WILL LIKELY PRODUCE A SWATH OF SNOW AND STRONG WINDS FROM
NORTHERN IDAHO DOWN THROUGH WESTERN IOWA TODAY. MODERATE IMPACTS
MAINLY DUE TO BLOWING SNOW ARE EXPECTED ACROSS MUCH OF WYOMING,
THE COLORADO ROCKIES, SOUTH DAKOTA AND NORTHWESTERN NEBRASKA. SNOW
OVER THE NORTHERN ROCKIES COULD ACCUMULATE BETWEEN 6-12 INCHES
WITH ISOLATED HIGHER AMOUNTS POSSIBLE. SNOW AND WIND SHOULD
SUBSIDE ACROSS THE NORTHWEST TONIGHT AS THE LOW PRESSURE SYSTEM
TRACKS INTO THE OHIO VALLEY.
DOWNSTREAM, ANOTHER, DEEPER MID-LATITUDE CYCLONE WILL SPREAD
SHOWERS AND SCATTERED THUNDERSTORMS INTO THE NORTHEAST WITH SOME
LIGHT SNOW SHOWERS POSSIBLE DOWNWIND OF THE LOWER GREAT LAKES
TODAY. THE ARRIVAL OF THE PLAINS SYSTEM WILL PROMOTE EVEN MORE
SNOW SHOWERS FOR THE BROADER GREAT LAKES REGION ON TUESDAY.
MUCH ABOVE AVERAGE TEMPERATURES ARE EXPECTED TO CONTINUE ACROSS
THE CENTRAL AND EASTERN U.S. TODAY AHEAD OF THEIR RESPECTIVE LOW
PRESSURE SYSTEMS. TEMPERATURES OVER SOUTH TEXAS WILL BE ESPECIALLY
ANOMALOUS WITH HIGHS LIKELY BETWEEN 20-30 DEGREES ABOVE AVERAGE.
NUMEROUS HIGH TEMPERATURE RECORDS MAY BE TIED OR BROKEN AS A
RESULT. UNUSUALLY MILD CONDITIONS IN THE NORTHEAST MAY ALSO TIE OR
BREAK HIGH TEMPERATURE RECORDS TODAY. A COOLING TREND ENSUES
ACROSS THE WEST TODAY BEFORE EXPANDING EAST THROUGH THE REST OF
THE COUNTRY OVER THE NEXT COUPLE OF DAYS. A CRITICAL FIRE WEATHER
AREA WAS ISSUED BY THE STORM PREDICTION CENTER FOR MUCH OF THE
SOUTHERN HIGH PLAINS FOR TODAY DUE TO THE ESPECIALLY WARM
TEMPERATURES PAIRED WITH DRY AND GUSTY WESTERLY DOWNSLOPE FLOW
BENEATH THE STORM TO THE NORTH.
