For the 23/06z TAF issuance.

Aviation
An upper level disturbance is moving away from the forecast area
currently. Only a few showers will remain in the vicinity of kara
through about 23/09z, otherwise, low ceilings with MVFR lowering
to ifr will be the main issue during the overnight. Ceilings will
gradually improve during Tuesday morning with MVFR toVFR after
23/18z. Another upper level disturbance will move across during
Tuesday evening. Will add vcsh at all TAF sites after 24/00z.

update... Rain chances continue to decrease across the region this
evening, however rainfall rates in the remaining stronger storms
is still fairly high. Will keep the ff watch for now until the
convection exits. Also modified the pops to reflect current
trends, but overall the previous forecast remains on track.

discussion...

short term... Tonight through Tuesday...

regional radar imagery shows light to moderate rain continuing
across the region this afternoon. There have been a few isolated
thunderstorms that have developed over the coastal waters;
however, more widespread convection has not developed. Overall
trend in the forecast has been for lower rainfall totals this
evening and tonight given the stratiform nature of the
precipitation. There is still a small chance for some minor
flooding and no changes to the flash flood watch will be made with
it currently set to expire at 1 am tonight.

The cold front that has been providing forcing for the showers and
thunderstorms over the past two days will begin to exit the region
late in the day on Tuesday. This will result in another chance of
showers and thunderstorms, mainly during the evening hours. The
cold front is expected to clear the CWA by late tomorrow evening
with northwest winds ushering drier air into the region.

Long term... Wednesday through Sunday...

a 500 hpa upper level ridge and associated surface high pressure
will build into the region for the second half of the work week.

Cooler conditions are expected on Wednesday with cold air
advection over the region. Wednesday night into Thursday is also
expected to have an ideal setup for radiational cooling with clear
skies and light winds. Onshore flow is expected to redevelop
Thursday and temperatures will return to normal for early summer.

The next chances for rainfall is expected late into the weekend as
the next shortwave trough approaches the region.

Marine...

showers and isolated thunderstorms will continue over the coastal
waters through the overnight hours. Winds will decrease as this
first round of showers and storms exit the region and small craft
exercise caution conditions are expected to end by morning.

Another round of showers and thunderstorms will be possible
Tuesday as a cold front moves across the coastal waters. Winds
will increase behind the front and could result in small craft
exercise caution conditions Tuesday night. Offshore flow will be
in place over the coastal waters through Thursday.

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.
