SHOWS WINDS IN THE 15-20 KT RANGE NOT TOO FAR OFF THE DECK WITH
TEMPS ALSO STAYING UP A BIT WARMER THUS FAR THIS EVENING. CURRENT
FORECAST HAS LOWS IN MID-UPR 30S TO LWR 40S MARTIN COAST. WILL NOT
CHANGE MUCH BUT MAY BE A BIT WARMER WITH THE CIRRUS AND WINDS A BIT
SLOWER TO DROP OFF. WILL KEEP PATCHY FROST ACROSS MAINLY NRN
INTERIOR SECTIONS LATE TONIGHT.

TUESDAY OUTLOOK...THE MODELS CONTINUE TO ADVERTISE A POTENT LOW

FURTHER INLAND.

COOL DRY AIRMASS BEHIND THE LOW WILL BRING MINIMUM RHS INTO THE 30 -
35 PCT RANGE OVER INLAND COUNTIES FROM WEDNESDAY AFT THROUGH FRIDAY.
