DISCUSSION:
COLD FRONT APPROACHES FROM THE WEST LATE SUNDAY NIGHT INTO
MONDAY, WITH THE POSSIBILITY OF A WAVE OF LOW PRESSURE
DEVELOPING ALONG THE FRONT AND TRACKING NORTHWARD MONDAY.
GREATEST UNCERTAINTY WITH THE RAINFALL DURING THIS PERIOD IS HOW
LONG IT LASTS AND TOTAL AMOUNTS, WHICH WILL DEPENDING ON
POTENTIAL WAVE DEVELOPMENT. SHOULD THE WAVE DEVELOP, PERIODS OF
RAIN MAY CONTINUE THROUGH MUCH OF MONDAY, WITH GREATER AMOUNTS
OF RAINFALL POSSIBLE. ON THE OTHER HAND, THERE STILL REMAINS A
CHANCE OF A MORE PROGRESSIVE FRONTAL SYSTEM WITHOUT WAVE
DEVELOPMENT, WHICH WOULD RESULT IN RAIN TAPERING OFF EARLIER
MONDAY WITH LOWER RAINFALL AMOUNTS. LATEST 01Z/FRI NBM HAS
24-HOUR PROBS ENDING 8 PM MONDAY FOR RAINFALL > 0.5" AT 60-75%
ACROSS THE REGION, WITH SIMILAR PROBS FOR RAINFALL > 1" OF
