TIGHTLY WOUND LOW PRESSURE SYSTEM CURRENTLY CENTERED JUST EAST OF
THE FORECAST AREA WILL SLOWLY MOVE NORTHEAST AND REACH THE OMAHA
AREA BY 12Z SUNDAY. WIDESPREAD SNOW WITH WIND GUSTS OVER 60 MPH
WILL MAXIMIZE THEMSELVES BY 00Z TONIGHT AND CONTINUE THROUGH AT
LEAST 06Z TONIGHT GENERALLY ALONG AND NORTH OF A KIT CARSON
THROUGH SHERMAN TO RED WILLOW LINE. SNOWFLAKES ARE RATHER LARGE
WHICH SHOULD HELP IN GETTING VISIBILITIES DOWN TO OR LESS THEN 1/4
MILE IN THE BLIZZARD WARNING AREA. FOR AREAS SOUTH OF THE
INTERSTATE PRECIPITATION WILL TAKE A BREAK AS 700-500 LAYER
DECREASES IN AVAILABLE MOISTURE TIL AFTER 06Z WHEN IT AGAIN
INCREASES ON THE BACKSIDE OF DEPARTING LOW. WILL KEEP SOME LIGHT
SNOW IN THE FORECAST THROUGH 18Z SUNDAY WHEN AFTER THAT TIME
MOISTURE WILL QUICKLY DECREASE FROM NORTHWEST TO
SOUTHEAST....BRINGING AN END TO THE EVENT. NORTHWEST WINDS OF 20
TO 30 MPH WITH HIGHER GUSTS ARE EXPECTED THROUGH THE DAY AND WHEN
COUPLED WITH AFTERNOON TEMPERATURES IN THE 30S MAKE FOR UNPLEASANT
CONDITIONS OUTSIDE. SNOW COVER WILL IMPACT TEMPS A BIT BUT WITH
850 TEMPS GENERALLY IN THE 20S IT WONT MATTER MUCH.

FOR MONDAY AND TUESDAY UPPER LEVEL RIDGING WILL BUILD INTO THE
AREA FROM THE WEST AHEAD OF ANOTHER LOW PRESSURE SYSTEM WHICH BY
00Z WEDNESDAY WILL REACH THE CALIFORNIA COASTLINE. TEMPERATURES
WILL WARM EACH DAY (POSSIBLY STILL IMPACTED BY SNOW COVER MONDAY)
WITH READINGS BY TUESDAY IN THE UPPER 50S EAST TO MID/UPPER 60S
WEST/SOUTHWEST.

WEDNESDAY SHOWING SOME DIFFERENCES IN THE HANDLING OF THE
CALIFORNIA SYSTEM AS IT MOVES INTO THE WESTERN STATES. WILL TREND
WITH THE ECMWF/CANADIAN SOLUTION WHICH IS A BIT SLOWER.
TEMPERATURES NEAR NORMAL WITH A SLIGHT CHANCE OF PRECIP ACROSS THE
WESTERN 1/3 OF THE AREA BUT CONFIDENCE REALLY NOT ALL THAT
HIGH...LATER SHIFTS WILL NEED TO ADDRESS.

FOR WEDNESDAY NIGHT AND THURSDAY SOME AGREEMENT IN THAT THE UPPER
LOW WILL MOVE TOWARD SOUTHEAST COLORADO AS AN OPEN
WAVE...SOMETHING TO WATCH GIVEN THE PAST 3 OR SO PRECIPITATION
EVENTS. KEPT SLIGHT CHANCE/LOW CHANCE POPS IN THE FORECAST WITH
TEMPERATURES BELOW NORMAL.

ON FRIDAY AND SATURDAY UPPER RIDGE REBUILDS OVER THE AREA BUT BY
THE END OF THE DAY SATURDAY LOW PRESSURE OR AT LEAST A TROUGH
MAKES ITS WAY TOWARD THE AREA. GFS HAS THE UPPER LOW OVER
SOUTHEAST COLORADO BY 12Z SUNDAY WHILE THE ECMWF HAS IT OVER
SOUTHWEST TEXAS. STAY TUNED.
