Prev discussion issued 423 am cdt Sat mar 23 2019
near term now through Saturday night ... A deep layer ridge of high
pressure will continue to dominate the area today. As the ridge
slides east this afternoon a light southerly flow will develop
across coastal areas. Clear skies, light winds and low humidity will
continue today with slightly higher humidity along the coast due to
the developing onshore flow. Highs today will climb into the low to
mid 70s and lows tonight will fall into the mid 40s inland to low
50s along the coast. 13
short term Sunday through Monday night ... A broad area of
surface high pressure over the western atlantic will create
a southerly wind flow over the area on Sunday. Aloft, a dry zonal
flow will prevail. Clear to mostly clear skies are expected
Sunday, but mid and high level cloud cover will begin to advect
into the area Sunday afternoon ahead of a developing upstream
frontal system. High temperatures Sunday will be well above
normal, climbing into the mid 70s to near 80 degree mark.

Increasing cloud cover and southerly winds will also keep the
overnight lows considerably warmer, ranging from the mid 50s to
near 60s along the coast.

A cold front will push southeastward across the region Monday
afternoon and evening. Guidance has been consistent in projecting
enough ascent along and ahead of the approaching front to trigger
scattered to locally numerous showers across our region. The best
development is expected to develop over our interior zones by
Monday afternoon. Enough instability will exist for the
development of thunderstorms, but the overall amount of
instability and shear appear limited enough to keep the overall
severe weather potential low Monday afternoon into early Monday
evening. Lingering, light post frontal showers will continue into
Monday evening. The frontal boundary is expected to move out over
the gulf by midnight with light showers ending several hours
later. Highs Monday will warm into the mid to upper 70s, while
lows Monday night will fall into the upper 40s to lower 50s
inland, with mid to upper 50s near the coast.

Long term Tuesday through Friday ... Another dry weather pattern
develops on Tuesday and continues into Friday. Included a slight
chance of light rain showers Friday afternoon ahead of an upstream
developing frontal system. Model to model agreement and run to
run consistency has been lacking on the development and timing of
this system. Suspect any significant chance of precipitation will
not occur until after Friday. Temperatures will trend cooler than
climatological norms Tuesday through Wednesday... Near normal on
Thursday and warmer than normal Thursday night and Friday.

Marine... A light onshore flow will develop this afternoon
through Sunday as a ridge of high pressure to the north shifts east.

Westerly winds and seas will build on Monday in response to a cold
front approaching from the northwest. The cold front is expected to
move across the marine area Monday night into early Tuesday leading
to a moderate to strong northerly flow and higher seas through
midweek. 13

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.
