...ISOLATED MOUNTAIN THUNDERSTORMS TODAY AND SUNDAY...
...PERIODICALLY BREEZY NORTH TO EAST WINDS AND LOWERING
HUMIDITY SUNDAY NIGHT THROUGH TUESDAY...
.DISCUSSION...
Isolated showers and thunderstorms over the mountains through
Sunday from lingering moisture. Storms will be wet, but any
lightning outside of the main precipitation core will bring the
potential for new starts and elevated fire weather concerns.
Periodically breezy north to east winds will then develop Sunday
night through Tuesday. High confidence in warmer and drier
weather returning early next week with above normal temperatures
and lower daytime and overnight relative humidity. Potential for another
push of moisture to bring renewed shower and mountain
thunderstorm chances mid next week mainly south of Interstate 80,
although confidence is low.
