Area Forecast Discussion
National Weather Service New Orleans LA
359 PM CDT THU AUG 18 2016
.DISCUSSION...
Please refer to our web site, Flood Warnings and the Advanced
Hydrologic Prediction Service for details on the major and record
river flooding that is still ongoing on the lower end of the Amite
River basin along with many areas of backwater flooding from
Pointe Coupee Parish (False River area) to near Lake Maurepas.
Few changes were made to the previous forecast package. Overall,
a fairly typical summer weather regime will persist into the
weekend with a Bermuda ridge extending from the the western
Atlantic into the northern Gulf of Mexico. There will be a daily
chance for convection with POPs near climatological normals for
this time of the year. Precipitable water values will generally
range between 1.75 to 2.0 inches through the weekend, however the
GFS indicates values spiking up near 2.25 inches in the afternoon
Friday in the northwest. Temperatures should also be near
seasonal normals through the weekend, with a few spots possibly a
little higher. Afternoon heat index values will be mostly in the
100 to 105 degree range.
A strong shortwave trough is forecast to move from the northern
Rockies into the northern and central plains Friday into Saturday
morning, and the upper Mississippi Valley, Great Lakes, mid
Mississippi Valley and Ohio Valley Saturday afternoon through
Sunday night. This will push a cold front far to the south into
the Gulf Coast states, with the front possibly stalling out across
northern sections of the forecast area Monday before washing out
by mid week. This will likely just maintain a decent chance of
showers and thunderstorms, early in the week, but the upper level
ridging over the Gulf Coast region should result in more isolated
convection by the middle of next week.
&&
.AVIATION...
Scattered convection has again developed over much of the area.
Can't preclude thunder at any of the terminals this afternoon and
will carry VCTS at all sites. Will use TEMPO TSRA for those
locations impacted directly for an hour or two. Will see MVFR/IFR
restrictions where direct impacts are anticipated, as well as
gusts to around 30 knots. Most or all convection should dissipate
around 00Z. MVFR ceilings were not as widespread this morning as
they were on Wednesday morning. For right now, will only carry
those ceilings at KMCB, KHDC, KASD and KGPT. Improvement again by
14Z-15Z window, and will likely see convection get going again
Friday around 17Z-18Z.
&&
.MARINE...
A rather benign weather regime will dominate the coastal waters
through early next week. Winds will generally be from southerly
5 to 10 knots and seas will generally range from 1 to 2 feet
through the weekend. Winds are expected to at least temporarily
become variable early next week as a weak cold front moves south
near the central Gulf coast and stalls out.
