Please keep in mind, even when the hurricane season ends, I have to keep up on these site subscriptions for severe weather and winter weather.

Greetings to everyone!
Please be aware, even though I do not post every night, rest assured I am continuously monitoring various areas for any significant weather.  I will be taking Sundays off (family time), unless we have active systems that may be posing a threat (i.e. Tropical, Winter Weather, Coastal Storms, etc.).

Good evening,
This update will be based on a short term forecast for the next 96 hours, out to the morning of 10 JAN.

Based on analysis this evening of the recent run of MSLP normalized anomaly maps, another low pressure system is forecast to develop over the Gulf coast states, beginning late tomorrow afternoon.  This system will track across LA., MS., AL., and a portion of FL. and GA.  Surface winds should increase along the coastal areas as this system moves toward the east. This low should exit off the coast of SC. and GA. by Friday morning.  once the center of this low reaches the coast, it will begin to deepen, and will briefly become a coastal storm.  By Saturday, the low will begin to move away from the coast and continue to deepen.  As this occurs, surface winds will become strong as the system strengthens near the coast, and cover a greater area as it moves away from the coast.  Strongest winds will be confined to a moderate area offshore and near the center of the low, and will cause some very high seas which could be dangerous to commercial shipping.  Areas effected by onshore winds could see some minor beach erosion and possible minor flooding along the immediate coast at high tide.  Small craft are urged to remain in port.

SURFACE WINDS FORECAST (MPH)


ECMWF WAVE HEIGHT AND DIRECTION FORECAST

The system will be responsible for bringing some snow to Arkansas, and then east into the Tennessee Valley and into a portion of the Mid Atlantic over a portion of Virginia and North Carolina.  Accumulated snowfall totals do not appear to be too great during the forecast period.  Precipitation over the Gulf coast states and FL. should be in the form of rain.

PRECIPITATION TOTALS BY PRECIPITATION TYPE


Colder temperatures will be in order for most of the U. S., however I do not expect Arctic air during the period.  Much colder minimum temperatures seem to be in order just after the 10th of JAN.
