DISCUSSION
ISOLATED SHOWERS AND THUNDERSTORMS WILL REMAIN POSSIBLE THIS AFTERNOON,
WITH DIMINISHING CHANCES OF PRECIPITATION INTO THE EVENING AND OVERNIGHT
PERIOD. ANY PRECIPITATION TODAY IS EXPECTED TO BE ON THE LIGHTER SIDE (AT
OR BELOW A TENTH OF AN INCH).
PRECIPITATION POTENTIAL WILL GRADUALLY RAMP UP AGAIN THROUGH THE MORNING
ON TUESDAY WITH DEVELOPMENT OF SCATTERED RAIN SHOWERS IN THE AREA. AS HEALTHY
NORTHEAST WINDS DEVELOP DURING THE DAY, RAIN WILL BECOME MUCH MORE PERSISTENT
AND ALSO GAIN INTENSITY, PARTICULARLY MID-MORNING THROUGH THE AFTERNOON.
AVERAGE HOURLY RAINFALL ACCUMULATIONS ARE EXPECTED TO RANGE BETWEEN 0.05-0.15",
BUT COULD OCCASIONALLY APPROACH 0.20-25"/HR UNDER ANY HEAVIER SHOWERS. RAIN
WILL BECOME NOTABLY LIGHTER LATE EVENING AND OVERNIGHT INTO WEDNESDAY
MORNING. THE CHANCE OF ANY THUNDERSTORMS WILL BE QUITE LOW (<10%).
TOTAL RAIN ACCUMULATIONS THROUGH MIDDAY WEDNESDAY ARE EXPECTED TO RANGE
BETWEEN 1.25" AND 1.75", WITH THE BULK OF THE ACCUMULATION OCCURRING LATE
TUESDAY MORNING THROUGH TUESDAY EVENING.
PRECIPITATION ASIDE, EXPECT COOLER TEMPERATURES ON TUESDAY WITH A HIGH
TEMPERATURE IN THE MID/UPPER 40'S, AND A CHILLY BREEZE OUT OF THE NORTHEAST.
