HARD FREEZE IS EXPECTED FOR THE LOW DESERTS FROM TUCSON WESTWARD
THURSDAY MORNING AND FRIDAY MORNING.

&&

.DISCUSSION...COOL NORTHWEST FLOW OVER THE AREA THIS MORNING IN WAKE
OF SYSTEM THAT WENT THROUGH THE AREA ON MONDAY. SEVERAL UPSTREAM
PIECES OF ENERGY ALOFT WILL CARVE OUT A VERY COLD UPPER LEVEL TROF
ACROSS NEW MEXICO AND ARIZONA OVER THE NEXT 24-48 HOURS. VERY COLD
ARCTIC AIRMASS...PLAINLY SEEN ON INFRARED IMAGERY THIS MORNING OVER
MONTANA AND WYOMING...WILL DIVE SOUTH ACROSS ARIZONA AND BRING THE
COLDEST FEBRUARY TEMPERATURES TO THE AREA IN OVER 20 YEARS. NOT ONLY
WILL THE OVERNIGHT LOWS BE NEAR RECORD COLD...BUT THE DAYTIME HIGHS
WILL BE VERY UNSEASONABLY COLD WITH MOST LOCATIONS SETTING DAILY
RECORD LOW MAXIMUM TEMPERATURES ON WEDNESDAY AND THURSDAY. LATEST
MOS GUIDANCE HAS COME IN A BIT COLDER...SO HAVE LOWERED BOTH HIGHS
AND LOWS FOR WEDNESDAY AND THURSDAY. HOWEVER I MAY NOT BE COLD
ENOUGH WHEN YOU LOOK AT ENSEMBLE AND BIAS CORRECTED TEMPERATURES.
HOW EXTREME IS THIS COLD AIR? I AM FORECASTING BACK-TO-BACK DAYS
WITH HIGHS LESS THAN 45 DEGREES AT THE TUCSON AIRPORT. IN THE 118
YEARS OR RECORD KEEPING IN TUCSON...THIS HAS HAPPENED ONLY ONCE
/1956/ IN FEBRUARY. A LISTING OF RECORD LOW TEMPERATURES ACROSS
SOUTHEAST ARIZONA FOR FEBRUARY 2ND AND 3RD CAN BE FOUND IN THE
CLIMATE SECTION BELOW.

HARD FREEZE MOST DEFINITE FOR ALL OF PIMA COUNTY AND SOUTH CENTRAL

HARD FREEZE WATCH FOR THESE AREAS. WITH GUIDANCE COMING IN A BIT
COLDER FOR TONIGHT I WENT AHEAD AN ISSUED A FREEZE WARNING FOR THE
SAME AREAS IN THE HARD FREEZE WATCH...EVEN THOUGH WE HAVE FREEZING
TEMPERATURES WITHIN THE PAST SEVERAL 30 DAYS.

FOR PRECIPITATION...WILL MAINTAIN SLIGHT CHANCE TO CHANCE OF SNOW

MENTIONED DISTURBANCES SQUEEZE OUT LINGERING MOISTURE. NOT EXPECTING
MUCH ACCUMULATION...WITH THE WHITES POSSIBLY SEEING UP TO TWO INCHES
OF DRY FLUFFY SNOW.

MID-LEVEL GRADIENTS WILL TIGHTEN OVER THE HIGHER TERRAIN FROM TUCSON
NORTHEAST TO THE WHITE MOUNTAINS. WIND SPEEDS OF 10-20 MPH WITH
LOCALIZED GUSTS TO 30 MPH WILL COMBINED WITH TEMPERATURES OF BETWEEN
5 ABOVE AND 5 BELOW TO PRODUCE WIND CHILL VALUES BETWEEN 15 TO 30
BELOW ZERO...WITH THE COLDEST READINGS IN THE WHITE MOUNTAINS. I
SERIOUSLY CONTEMPLATED ISSUING A WIND CHILL WATCH FOR THE WHITE
MOUNTAINS. TO THE BEST OF MY KNOWLEDGE...IN THE 16 YEARS I'VE BEEN
IN ARIZONA WE AS AN OFFICE HAVE NEVER ISSUED THIS PRODUCT. WILL PASS
THIS IDEA ON TO THE DAYSHIFT TO PONDER.

HEIGHTS/THICKNESS VALUES RECOVER OVER THE WEEKEND FOR A RAPID
WARMING TREND UNDER DRY NORTHERLY FLOW ALOFT.
