Synopsis A surface trof will move across the area tonight
followed by a weak cold front Monday afternoon. Upper level low
pressure will linger north of the great lakes Monday night
through the remainder of the week with persistent weak high
pressure over the mid-atlantic.

Near term through tonight Dense fog has formed across the
northern part of the fcst area with many sites reporting less
than a quarter mile visibility.

For today, weak sfc front trof will get hung up across the area
today and this evening with models indicating decent sfc
convergence across the NRN part of the fcst area. A shortwave-
trough will move across the area this evening and help trigger
numerous to widespread showers and t-storms. Overall, trend in
the models and ensembles the past 24 hrs is for weaker sfc
convergence and less QPF than yesterday. Despite this, there is
still some concern for flash flooding mainly across the far
northwest part of the fcst area where sfc convergence lift will
be strongest and a plume of 1.5+ inches of pw will advect in.

1-2 inch hourly rain rates can be expected with heaviest
showers. Isolated instances of flash flooding are possible
mainly across allegany, mineral, and grant counties. Think
severe threat will be more limited due to plenty of cloud cover
and weak instability below 1000 j kg.

Short term Monday through Tuesday night Things will calm
down somewhat as drier air filters in on westerly flow, but it
won't be completely dry. Still risk of showers t-storms tue
afternoon as a weak cdfnt moves through.

Long term Wednesday through Saturday
The upper level pattern for the middle and end of the week will
feature a closed low drifting across eastern canada. While
increasing model spread of this feature late in the week lends some
uncertainty, there is some signal in the noise.

On Wednesday, a weak cold front will be drifting south of the area.

There are some indications this front could waver, resulting in
lingering chances of showers, but eventually high pressure building
from the west should lead to higher probabilities of dry conditions.

Thursday has the highest probability of being dry this week. Return
flow will begin on Friday, although forcing instability aren't that
notable. A cold front will be sinking southward next weekend,
although progress will be slow since it will be parallel to the
upper flow. Thus an unsettled period appears probable, but timing is
uncertain.

Temperatures will settle close to normal behind the front on
Wednesday and Thursday, then warm back up (highs in the 80s) ahead
of the next front on Friday and Saturday.

Aviation 08z Sunday through Thursday Lifr conditions
through 12z today at kcho and kmrb due to dense fog. Then,
showers and t-storms this afternoon and evening with brief
MVFR ifr CIGS in t-storms with heavy rain.

Overall Wednesday should beVFR, but there is a small chance of
showers as a front sags south of the area. Winds could also gust
around 20 kt.VFR conditions are expected Thursday as high pressure
builds in from the west.

Marine Winds should remain below SCA through the first half
of the week, but higher winds and waves can be expected near
thunderstorms.

Depending on the position of a cold front, winds could near sca
levels on Wednesday but confidence is low. Lighter winds are
expected on Thursday as high pressure builds in from the west.

Tides coastal flooding Water anomalies will continue to rise
through 12z Mon with minor coastal flooding expected at many of
the coastal sites. Winds turn westerly on mon, but they will be
generally light and may not be able to lower anomalies that
much.

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.
