DISCUSSION
ISSUED AT 126 PM CST SAT FEB 22 2025
LONG-AWAITED WARMUP HAS BEGUN AS TEMPERATURES HAVE REACHED THE MID
30S OVER CENTRAL AND SOUTHEAST ILLINOIS THIS AFTERNOON. VISIBLE
SATELLITE IMAGERY SHOWS A FAIRLY LARGE AREA OF NEARLY BARE GROUND
OVER THE FORECAST AREA NORTH OF I-70, AND THIS REGION WILL BE THE
MILDER AREA THROUGH SUNDAY, POTENTIALLY REACHING NEAR 50 DEGREES
IN WEST CENTRAL ILLINOIS. HOWEVER, COOP REPORTS AND NOHRSC
ANALYSIS INDICATES SNOW DEPTHS IN SOUTHEAST ILLINOIS ARE ONLY
AROUND AN INCH OR TWO, SO THIS WILL ERODE NICELY THIS WEEKEND AS
TEMPERATURES STILL GET WELL INTO THE 40S.
WITH THE AIR MASS REMAINING OF PACIFIC ORIGIN MUCH OF THE UPCOMING
WORK WEEK, HIGHS IN THE 50S WILL BE COMMON, CLOSE TO THE 75TH
PERCENTILE FROM NBM GUIDANCE. A LOOK AT ENSEMBLE TEMPERATURE
ANOMALIES SUGGEST TEMPERATURES RETURNING CLOSER TO NORMAL FOR THE
FIRST WEEKEND OF MARCH.
THE OVERALL WEATHER PATTERN DOES NOT LOOK ESPECIALLY ACTIVE DURING
THE PERIOD. WHILE A SHORTWAVE DROPS SOUTHEAST THROUGH THE AREA
MONDAY NIGHT, IT WILL BE FAIRLY MOISTURE-STARVED, AND RAIN CHANCES
SHOULD BE LIMITED TO AROUND 20-30%. A DEEPER UPPER TROUGH DIGS
ACROSS THE MISSISSIPPI VALLEY WEDNESDAY NIGHT WITH A LITTLE MORE
MOISTURE, BUT NOTHING OF SIGNIFICANCE (EUROPEAN ENSEMBLES SHOW
CHANCES OF MORE THAN 0.10 INCH OF RAIN ARE ONLY AROUND 30-40%).
