300 am cst Wed nov 22 2017

Short term
Upper analysis shows a southern stream trough moving into the
northwestern gulf of mexico, a northern trough draped across the
great lakes and appalachian mountains, and ridges well to the east
and west. Radar imagery shows rainfall associated with the southern
trough is moving south and will be a mostly coastal issue by
daybreak. Things are slightly more complex at the surface.

Observations show that the southern disturbance has drawn some drier
air into the CWA ahead of the actual cold front to the north. This
has induced development of a prefrontal surface trough. It will be
moving south across the area over the next few hours. The
continental air mass associated with the northern upper trough will
likely not reach the northern CWA zones until late morning and track
across the area through the early afternoon. This cold front will be
bringing another round of cold mornings with temperatures falling
into the 30s thanksgiving and Friday.

Long term
The CWA will generally remain under troughing going through this
weekend. Temperatures will try to rebound Saturday as the upper
level pattern bulges east before another trough dives southeast out
of canada across the northeastern us. In response to this, a
reinforcing cold front will swing through the forecast area Saturday
night and keep the area below normal through Monday.

A change in the pattern will finally take place early next week.

Upper ridge that had been stationary to the west of the region will
track east across the gulf south late Monday through late Tuesday.

Increasing column heights will allow for temperatures to return to
normal or slightly above. Both GFS and ECMWF show a trough following
the movement of the ridge and bring the next chance of rainfall to
the cwa.

Meffer

Aviation
Lowest ceilings will dissipate rapidly this morning as a cold front
moves through. Ceilings will run ovc120+ for the next few hours
after ceilings at 030 clear and total clearing will occur toward
late morning for most and all sites by afternoon.VFR through this
taf cycle.

Marine
Winds will abruptly rise today as a disturbance moves through the
coastal waters. This disturbance will get forced south this morning
by an approaching cold front that will move through the northern
gulf clearing things out late today but causing winds to remain
elevated. Between the disturbance getting forced south and the front
moving in, winds will ease a bit back to around 15 to 20kt this
afternoon. The front will pass by late afternoon and early evening
causing winds to rise abruptly once again. Since winds will only
ease a bit this afternoon before rising once again, the advisory
will remain posted through this period as well.

Winds ease by the end of the week as high pressure settles across
the northern gulf. Saturday looks like the lightest wind day at the
moment as it transitions from high pressure to a new front moving
through for Saturday night into Sunday. Return flow to become better
established by the start of next week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
