Prev discussion issued 454 am cdt Mon mar 18 2019
near term now through Monday night ... Surface high pressure over
the plains shifts east though tonight, with the forecast area
remaining under dry, cooler northerly flow. A weak cold front will
move south across the forecast area later today through tonight,
helping to re-enforce the dry airmass over the region. With the
dry nature of the front, temperatures will be main forecast issue.

Mostly sunny skies today and the dry airmass over the area will
be counter-balanced by the cold advection, limiting today's high
temperatures to the upper 60s, a bit under seasonal norms for the
date. For tonight, a passing mid level shortwave will bring
increasing cloud cover overnight, helping to limit the effects of
the continued cold advection and a dry airmass. Still, am
expecting overnight lows to drop to well below seasonal norms.

Lows ranging from around 40 inland to mid 40s along the coast
expected. 16
short term Tuesday through Wednesday night ... Large surface high
pressure across the eastern CONUS will move eastward over the
western atlantic through Tuesday night, but leave a surface ridge
across the southeast states into midweek. This will keep light
northerly winds, and a cool dry airmass across the forecast area
through the short term. A primarily zonal wind flow aloft will
occur through midweek, while an upper level shortwave over the
northern plains dives southeast, along with another upper level
shortwave diving southeast over the great lakes, carving out a
deep upper trough extending from southeast canada to the eastern
gulf of mexico. As it does, a highly amplified upper level ridge
will build over the nation mid-section Wednesday night. Therefore,
no rain remains in the forecast, along with clear to mostly clear
skies. High temperatures Tuesday will be around 5 degrees below
normal, ranging from 63 to 67 degrees. Low temperatures Tuesday
will be 7 to 12 degrees below normal, ranging from 33 to 39
degrees inland areas, with lower 40s along the coastal sections
and mid 40s at the beaches. High temperatures Wednesday will be
slightly warmer, ranging from 66 to 71 degrees. 22
long term Thursday through Sunday ... The deep upper trough will
move eastward over the western atlantic Friday night into the
weekend, while the upper level ridge moves eastward as well over
the eastern conus. This, along with a secondary surface high
pressure system building in from the northwest will act to
reinforce the cool, dry airmass across the forecast area through
Thursday before beginning to moderate. No rain remains in the
forecast through Saturday, along with clear to mostly clear skies.

High temperatures are forecast to be slightly below normal on
Thursday, followed by near normal to above normal temperatures
Friday through the weekend. Increasing clouds along with scattered
showers with a slight chance of thunderstorms will return on
Sunday as the upper level ridge advances eastward, low level
return flow sets up on a the backside of the exiting surface high
pressure, and upper level impulses traversing the forecast area.

22
marine... A weak cold front will move south over area waters later
today through tonight, bringing another round of moderate to
strong offshore winds to area waters. Have extended the current
sc.Y for most of our open gulf waters through tonight along with
adding the near-shore pns-dts zone. Surface high pressure over the
central northern plains will shift east to over the mid-atlantic
region through Tuesday night, bringing a light to moderate
offshore flow to area coastal waters later Tuesday into Wednesday.

A strong cold front will cross area waters Thursday, bringing
moderate to at times strong offshore flow for Thursday, but as
surface high pressure over the southern plains shifts quickly east
over the southeast Thursday night into Friday night, a light
offshore flow returns to area water by Saturday. 16

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.
