117 pm cdt Sun sep 23 2018

Updated for 18z aviation discussion.

Vfr conditions are expected to prevail through Monday with the
exception being during shra tsra and some possible MVFR cigs
Monday morning. Main forecast problem as always in this pattern
will be timing out the mainly brief impacts from scattered to at
times numerous shra tsra that are expected to increase in coverage
through the afternoon before decreasing this evening. Have mainly
indicated vcts in early portion of forecast with tempo TS later
this afternoon. 22 td

Prev discussion issued 325 am cdt Sun sep 23 2018

an upper level ridge is currently centered in the western
atlantic east of the carolinas while a weak upper trough is slowly
moving through texas. This trough as well as a northern stream
one have completely eroded any existence of a ridge over the cwa,
thus further decreasing local subsidence. Current radar shows
nocturnal isolated showers and thunderstorms in the coastal
waters. As typical with the current environment, daytime heating
will cutoff coastal region convection by mid morning before
sparking inland thunderstorms. It should be much like yesterday,
with 50 to 70% rain chances across the CWA this afternoon.

Generally speaking, higher rain chances should be on the western
side of the CWA as its further from the center of the upper ridge.

The hrrr and global models support this areal differentiation.

The main threat with storms today will be locally heavy rainfall
as pw's are around 2". Although most locations won't see more than
half an inch, upwards of 2 to 3" will be possible in isolated
incidents. Hail is unlikely with wbz close to 13kft but small
pebbles not impossible with very strong updrafts. However,
yesterday's 00z sounding does show enough dry air aloft to
possibly support strong downdrafts. A svr warning is not too
likely but a few sps' or ffw wouldn't be much of a surprise.

The forecast through early next week will basically be the same as
today with higher pops expected. From midweek onward, models show a
broad upper level trough pushing south into the midsection of the
country. A cold front associated with that trough will be pushing
south towards the area Thursday but should stall as is moves in.

This is due to the lack of southward progression of the base of the
trough. The GFS and ECMWF operational models are both quite close to
their ensemble members. The front will then quickly lift back north
as an upper level ridge builds across the southern third of the
country. No fall-like cold fronts this week.


expectVFR conditions to prevail outside of thunderstorms that
are expected to develop late in the morning into the afternoon
hours. Stronger storms may reduce CIGS and vsbys to ifr conditions


not much change in the forecast. A weak area of high pressure will
remain centered east of the forecast area and this will keep onshore
flow ahead of a frontal boundary northwest of the forecast area.

Winds around 10 knots or less and wave heights of 1 to 3 feet should
be the rule. Scattered showers and thunderstorms are expected
through the remainder of the weekend and into the early to mid part
of next week, so locally higher wind gusts and waves will be
possible. 13 td

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
