1/5 – Brittany’s “Clear & Mild” Thursday Evening Forecast
A bit cooler today, but overall a very beautiful day ahead across the lower Mississippi River Valley/North Central Gulf Coast. Aloft, a longwave trough resides over the southeast. Water vapor imagery and forecast soundings are very dry indicating plentiful sunshine today. Surface high pressure will continue to spread into the region, which should limit surface winds keeping things light and variable through the short term period. With the wind direction and dry at the surface, the sea fog machine will remain solidly in the off position.
Friday should be a carbon copy of today (sunny and seasonably mild) with only a few subtle differences. Toward the end of the period, upper level heights will gradually start to increase from west to east as the aforementioned upper trough beings to exit to our east. At the surface, in similar fashion the surface high pressure will continue spreading eastward into Florida allowing for a weak return flow to begin as we round out the short term.
