912 pm edt Sun mar 26 2017

Synopsis
A front will remain stationary across the area through this
evening then return as a warm front early Monday. Another cold
front will cross the area late Tuesday. High pressure will build
over the region Thursday.

Near term /through Monday/
A warm front is stretched from lake erie to central va this
evening. Easterly flow persists across the mid-atlantic and low
stratus and patchy drizzle will continue. Light rain has broken
out across the central foothills from southerly flow aloft
overrunning the frontal boundary in place. Another area of rain
will move e-ne across the highlands tonight. Hi-res guidance
keeps steady rain west of the blue ridge and across northern md
into Monday morning however on-off rain and drizzle are likely
further east into Monday morning.

The warm front will likely stay stationary overnight since low-
level flow is light. Temps will stay steady overnight. Patchy
fog is also possible across the dc and baltimore metros into
Monday morning.

The warm front will clear from south to north Monday morning.

Low clouds and patchy fog will last the longest across northeast
maryland Monday morning. Temps will soar back into the 70s
across much of the area by afternoon.

A weak convergence zone will exist/remain and combined with
some instability could be enough for scattered showers and an
isolated thunderstorm.

Short term /Monday night through Tuesday night/
Better forcing and moisture spreads across the area late mon
night and Tue with approach of low pressure and associated cdfnt
for better coverage of showers and thunderstorms.

Long term /Wednesday through Sunday/
Long term period starts dry as high pressure builds over our
region Wednesday into Thursday with high temperatures in the 50s
and 60s. Conditions will deteriorate Thursday night into Friday
as a low pressure system tracks east-northeast from missouri to
near lake erie. Its associated warm front will stay south of
the mid-atlantic into Friday before lifting Friday night. Low
pressure develops near or off of the DELMARVA peninsula Friday
night into Saturday as unsettled conditions continue over our
region. Conditions improve during the day on Saturday as low
pressure moves away from the coast. Dry conditions continue into
Sunday.

Aviation /01z Monday through Friday/
Ifr/lifr conditions tonight with cigs/vsbys improving to
MVFR/vfr mon. Ra/dz is possible at terminals overnight into
Monday. Shra/vcts possible Monday afternoon. Showers and
possible t-storms expected again on tue.

Dry/vfr conditions expected for Wednesday and Thursday before
rain approaches the area Thursday night, possibly bringing sub-
vfr conditions over the terminals into Friday.

Marine
Winds are expected to increase tonight across the southern
waters and SCA is in effect through Monday. Southerly winds will
weaken Monday night. Low pressure and a cold front will impact
the waters Tuesday and Tuesday night. SCA is likely during this
time.

Dry conditions expected for Wednesday and Thursday before rain
approaches the area Thursday night, bringing showers over the
waters into Friday. Wind gusts will be near the small craft
advisory threshold during parts of this period... Therefore sca
possible at times.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
