Bay Area residents might have to bundle up this week as a
cold-weather front brings a change to colder temperatures as early as
tonight, a National Weather Service forecaster said.
A "fast-moving" low pressure system is developing over the Pacific
Northwest and is heading south, forecaster Logan Johnson said today.
The front brings the possibility of the season's first frost in
North Bay valleys, where temperatures could drop into low to mid 30s Tuesday
through Thursday nights, Johnson said.
Low temperatures in the San Francisco area are expected to be in
the upper 40s, with highs in the upper 50s, according to the Weather Service.
Forecasters predict rain for Newark, California on Monday with a high of 55 and a low of 43. Fog may cloud the area on Tuesday.
There is a slight chance of rain across the Bay Area after
midnight tonight, Johnson said.
"Unfortunately for us, there is not a lot a moisture associated
with the system," he said.
High elevations in the South Bay have the highest chance of rain,
The Weather Service issued a wind advisory for Sunday night, when
gusts could reach 45 mph in higher elevations.
Northwest winds between 15 mph and 25 mph are expected throughout
the region tonight and should die down before sunrise on Monday, according to
the Weather Service.
