ROCKIES...

SOUTHERN PLAINS ON FRIDAY...
...MILD TEMPERATURES PERSIST ACROSS CENTRAL PART OF THE COUNTRY
THROUGH THIS WEEKEND...
A POWERFUL LOW PRESSURE SYSTEM WILL SPREAD WINTER, SEVERE AND RAIN
HAZARDS ACROSS WESTERN AND CENTRAL PARTS OF THE COUNTRY. TONIGHT,
HEAVY RAIN AND SNOW IMPACTS WILL COME TO AN END OVER CALIFORNIA,
WHILE TROPICAL AND SUBTROPICAL MOISTURE CONVERGE TO SPREAD SNOW
OVER THE GREAT BASIN INTERMOUNTAIN WEST AND ROCKIES. THIS SNOW
WILL CONTINUE WHILE THE LOW PRESSURE SYSTEM TRACKS ACROSS THE FOUR
CORNERS REGION ON FRIDAY. THE STORM SYSTEM WILL REORGANIZE OVER
THE CENTRAL/SOUTHERN HIGH PLAINS ON FRIDAY WHILE IT BEGINS TO TAP
MOISTURE AND INSTABILITY FROM THE GULF OF MEXICO. THIS MOISTURE
WILL INTERACT WITH A PROMINENT JET STREAK ALOFT AND STRONG
CONVERGENCE AT THE SURFACE ALONG A COLD FRONT AND DRYLINE. THIS
COMBINATION MAY PRODUCE SEVERE THUNDERSTORMS ACROSS OKLAHOMA/TEXAS
AND THE LOWER MISSISSIPPI VALLEY BEGINNING IN THE LATE AFTERNOON
ON FRIDAY. A SLIGHT RISK (LEVEL 2/5) OF SEVERE THUNDERSTORMS IS IN
EFFECT FOR PORTIONS OF SOUTH-CENTRAL TEXAS WHERE LARGE HAIL,
TORNADOES AND STRONG WIND GUSTS WILL BE POSSIBLE. THE FOCUS FOR
HEAVY RAINFALL AND THUNDERSTORMS WILL SHIFT INTO THE LOWER
MISSISSIPPI VALLEY AND CENTRAL GULF COAST ON SATURDAY WHERE THE
DEEP REDEVELOPED LOW PRESSURE SYSTEM WILL MOVE INTO. AS A RESULT,
A SLIGHT RISK (LEVEL 2/4) OF EXCESSIVE RAINFALL IS IN EFFECT FOR
PORTIONS EASTERN TEXAS, SOUTHERN ARKANSAS, LOUISIANA AND SOUTHERN
MISSISSIPPI ON SATURDAY.
AN OMEGA BLOCK RIDGE OVER THE CENTRAL U.S. WILL SUPPORT MILD
TEMPERATURES FROM THE GREAT PLAINS TO THE EAST COAST THROUGH THIS
WEEKEND. PORTIONS OF THE NORTHERN/CENTRAL PLAINS INTO THE
UPPER/MIDDLE MISSISSIPPI VALLEY WILL EXPERIENCE LOW TEMPERATURES
FROM THE UPPER 20S TO LOW 50S THROUGH EARLY NEXT WEEK, WHICH MAY
TIE OR BREAK EXISTING RECORDS. TEMPERATURES IN THE SOUTHERN PLAINS
WILL MODERATE A BIT BENEATH THE DEEPENING UPPER-LEVEL LOW ON
SATURDAY.
