track. 41

Prev discussion issued 403 pm cdt Mon apr 23 2018
a nice and quiet day with cumulus forming along the backside of a
slowly churning upper low just west of appalachia. Northwest
winds and mainly clear skies will prevail through Tuesday as lower
level high pressure moves across the central u.S.. Increasing
cloudiness with winds becoming more variable on Wednesday as the
region falls just downstream of an approaching shortwave trough
moving southeast out of the central rockies. Low end to (low end)
moderate pops associated with the surface boundary passage during
the late Wednesday evening through early Thursday morning hours.

The main question marks will be with moisture return and upper
level forcing (or lack thereof). With Wednesday's brief onshore
flow and mid-level westerly steering winds pulling in a more humid
south central texas air mass... There will not be enough time to
fully saturate the column by the early Thursday morning frontal
passage. Jet dynamics are not there as models indicate no low
level jet and a fairly zonal westerly flow pattern at 250-300 mb.

Any precipitation that forms appears to be along or just ahead of
the front itself. Ample lapse rates exist for any forced parcel
within the frontal zone to continue on an unimpeded upward trek.

Hence the relatively lower chances for mainly evening showers with
isolated storms and early Thursday scattered showers with
embedded thunder that will be focused over the northern 2 3rds of
the cwa.

Transitory ridging moving across the southern plains in the wake
of Thursday's mid atlantic upper troughing will equate to fair
weather leading into the weekend. Clearing skies and dry conditions
to end the week. Possibly some minor cooling Thursday as tmaxs
struggle to reach the upper 70s but, by Friday, subsequent days
will again warm into the lower 80s nights cooling into the middle
50s. Onshore winds and moisture return on Sunday with minor pops
painted out west to account for a possible weak disturbance passage
or two going into early next week. 31

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.
