1/4 – The Chief’s “High Pressure Moving In” Wednesday Morning Forecast
A cold front is currently east of the area moving east with a few lingering showers. Behind the front, very subtle Cold Air Advection will lag just a bit. With insolation during the afternoon hours, expect temperatures to again be above average across the area. CAA gets a bit stronger in time, which will help drop temperatures to more seasonal averages by later tonight and especially on the day Thursday. Surface winds will begin to transition to a more northwesterly direction, which will finally pull the plug on the sea fog machine…at least for the short term period. Otherwise, expect more tranquil weather for much of the short term, especially as surface high pressure spreads into the region by the end of the period.
Starting off the long term, temperatures will remain closer to average for early January. An upper level disturbance over the eastern US will continue downstream allowing for a weak upper high pressure to build into the region by Friday and into Saturday. With this taking place, some gradual warming/moistening will take place late week and especially into the upcoming weekend.
By Sunday, models show a surface front parked over the MS Delta Region up into the TN River Valley. Aloft, a parent trough will begin to amplify over the Ozarks southward to the NW Gulf Coast. At the surface, a return flow will have set up again helping bring moisture back into the region, however, at this stage the moisture quality looks a bit lackluster over our region with the best moist return over the upper TX Coast into the ArkLaTex region. This will allow a front and to move through the region fairly quickly.
