Synopsis
A cold front will trigger showers and thunderstorms over
southern areas through this evening. High pressure will crest
over the region on Tuesday before shifting offshore to the
southeast. A low pressure will slowly move northeast through

will drop southeast through the region Thursday night and
Friday. High pressure will gradually build in from the west over
the weekend.

Near term through tonight
A short wave trough will move across the region this evening,
and will be associated with scattered showers and thunderstorms.

Given the amount of moisture and CAPE along with steep low
level lapse rates, a few storms may be severe. Damaging winds
and torrential downpours will be the main threat. The threat for
storms ends by 00z as a short wave trough quickly moves
offshore. Clearing is expected tonight in the wake of the front.

Valley fog, some dense, is expected overnight. Some dense fog
will also be possible on the midcoast as well.

Short term Tuesday through Tuesday night
Fair weather expected Tuesday with short wave ridging in place.

a few thunderstorms across southern zones late.

Long term Wednesday through Monday
Unsettled weather through Friday and drier air will move in for the
weekend.

A frontal system to the south of the forecast area will move back
north with increasing chance of showers and thunderstorms through
Wednesday night. Dewpoint temperatures will climb back to near
70 on Wednesday afternoon. Wednesday will start out with chance
showers and thunderstorms with the warm front passage. The cold
front will pass through later in the day giving likely showers
and thunderstorms in the afternoon and evening.

Thursday will still be a warm day but dewpoint temperatures will be
a bit more comfortable. The cooler and drier air sets in for Friday
with dewpoints in the mid 50s or less. Showers possible in the

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
