Aviation
06z TAF discussion:
vfr conditions and clear skies are expected at area sites through
the next 24 hours. Temperatures will moderate some (compared to
what has been experienced lately) tomorrow, but not before a
frigid start. Anticipate generally light northerly to calm
northerly winds tonight picking up slightly from the west to
northwest during the day tomorrow at the surface. Any remaining
snow ice on the ground will melt by the afternoon tomorrow. Bb

Discussion
Evening surface analysis had a 1039mb high centered over our
western zones. This high will move very little the remainder of
the night and result in a light and variable wind. Under clear
skies and the light wind, strong radiational cooling will allow
temperatures to bottom out in the lower teens in most areas. Thus,
the hard freeze warning will remain in effect. No changes were needed
to the current forecast. 22
prior discussion below:
tonight and Thursday: one more night with widespread lows in the
teens before the arctic airmass finally begins to recede. Only a few
sites have reached freezing today, mainly those along the i-59
corridor. However, they will be quickly back below freezing within
the next hour as we begin to lose insolation. The good news for
tonight is winds will lighten as the surface ridge axis moves over
the area, meaning wind chills will no longer be a major concern. Of
course, that also means temperatures will still be dangerously low,
with most areas expected to bottom out in the lower teens. We could
again see some single digits, particularly in the areas with
lingering snow cover across the delta, and forecast lows were nudged
down a bit in those areas. Tomorrow under full sun, we should see
the entire area return to above freezing, though some locations may
only make it into the mid to upper 30s across the delta and hwy 82
corridor. Nevertheless, we should be able to allow the hard freeze
warning to expire as a slow thaw resumes. Dl
Thursday night through next Tuesday:
cold and dry conditions will continue Thursday night, with lows
ranging from the upper teens to the lower 20s.

We will see a warming trend Friday into the weekend. Highs Friday
look to be in the middle 40s to middle 50s under mostly sunny skies.

Dry conditions and warmer conditions are expected Saturday, with
highs mainly in the middle 50s to lower 60s. Rain will be moving
into the region Sunday into Sunday night in association with a
frontal system. Some thunderstorms will be possible with this
system, but not expecting any severe storms at this time. This is
still several days out, and will continue to be monitored. Highs
Sunday will be even warmer, ranging from the lower 60s to near 70.

Showers and thunderstorms will be moving out of the region on
Monday, with high pressure building in behind. Highs on Monday will
be in the middle 50s to lower 60s. Expect mostly sunny skies on
Tuesday with highs once again in the middle 50s to lower 60s. 27

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.
