DISCUSSION

THROUGH TOMORROW...
DANGEROUS COLD CONDITIONS ARE THE KEY HIGHLIGHT OF THIS FORECAST
PACKAGE. AN ARCTIC AIRMASS CONTINUES TO ENTRENCH ITSELF IN THE AREA
WITH OBSERVED TEMPS BELOW SEASONAL NORMS THROUGH THE DAY TOMORROW.
STRONG COLD AIR ADVECTION WILL CONTINUE THROUGH THE NIGHT AS
NORTHERLY WINDS REMAIN GUSTY. REFREEZING OF ANY LINGERING MOISTURE
WILL BE POSSIBLE TONIGHT, BUT THE PERSISTENT WIND SHOULD HELP
COUNTER THIS BY EXPEDITING THE DRYING PROCESS.
THIS WEEKEND...
THE SURFACE RIDGE WILL SHIFT EAST OF THE AREA, WITH A GRADUAL
MODERATING TREND IN TEMPS THROUGH SUNDAY. THIS WILL BE FOLLOWED BY A
SOUTHERN STREAM DISTURBANCE WHICH WILL TRACK WELL SOUTHWARD NEAR THE
GULF COAST. THIS WILL SPREAD MAINLY LIGHT RAIN NORTHWARD ACROSS
AREAS PRIMARILY SOUTH OF I-20 FROM EARLY SUNDAY MORNING THROUGH
SUNDAY AFTERNOON OR EARLY EVENING. WHILE CONDITIONS MAY BE RATHER
COOL SHORTLY AFTER SUNSET SATURDAY EVENING, GUIDANCE SHOWS
TEMPERATURES RISING OVERNIGHT SATURDAY NIGHT AHEAD OF THE RAIN,
KEEPING PRECIP IN A LIQUID STATE.
NEXT WEEK...
BROAD SURFACE HIGH PRESSURE WILL BUILD ACROSS THE CENTRAL CONUS
EARLY NEXT WEEK, RESULTING IN DRY WEATHER CONDITIONS IN OUR AREA AND
TEMPERATURES RETURNING TO ABOVE NORMAL BY THE MIDDLE OF THE WEEK.
