DISCUSSION
KEY MESSAGE 1...POTENTIAL FOR PATCHY FROST TONIGHT AND MONDAY
NIGHT ACROSS THE NORTH.
KEY MESSAGE 1 DESCRIPTION...
HIGH PRESSURE SYSTEM HAS SETTLED OVER QUEBEC TODAY. CONFIDENCE
IN FROST POTENTIAL IS RELATIVELY LOW, SINCE TEMPERATURES ARE
HEAVILY GOING TO DEPEND ON HOW FAST CLOUD DECK MOVES IN. UPPER
AIR MODEL SOUNDINGS INDICATE THE WEAK WINDS AT THE SURFACE WITH
LOWER SURFACE DEWPOINTS. THUS, LOWER RH VALUES WHICH SHOULD KEEP
FROST POTENTIAL LOW. BEST CHANCES FOR PATCHY FROST WILL BE IN
THE NORTH WOODS, AND CENTRAL/SOUTHERN AROOSTOOK.
HIGH PRESSURE WILL BUILD TOWARD THE REGION MONDAY NIGHT, WITH
CLEARING SKIES AND DECREASING WINDS. THIS WILL CREATE FAVORABLE
CONDITIONS FOR RADIATIONAL COOLING. PATCHY/AREAS OF FROST ARE
POSSIBLE ACROSS NORTHERN AREAS LATER MONDAY NIGHT, WITH THE
BETTER CHANCES IN THE NORMALLY COLDER LOW LYING AREAS.
