A fair trade
While below average temperatures are expected through Mardi Gras, so too are dry conditions.
Today and Tonight: Friday will be sunny with highs in the mid to upper 50s. The Krewe of Southdowns will have quiet, chilly weather for their evening parade which rolls at 7pm. We’re forecasting clear skies, light winds and a temperature in the mid 40s. Overnight will be cold again with lows in the mid 30s. A few passing clouds are possible.
Up Next: A weak front passing through the region on Saturday will bring a few clouds and possibly a stray, light shower to southern and western areas. With the Spanish Town parade rolling at noon, expect partly sunny skies and temperatures in the mid 50s. Afternoon highs will stretch for the upper 50s. Sunday Morning will start off chilly in the middle 30s with all sunshine and a high near 60 degrees in the afternoon. Another reinforcing shot of chilly air will arrive in time for Mardi Gras, but all clear skies are expected to continue.
Forecast Discussion: Surface high pressure will remain in place through today. Nudging towards the Southeast U.S., the system will continue to promote clear skies and light winds. Overnight, easterly winds should limit a temperature tumble all the way to freezing, but it will remain cold and in the mid 30s. Plus, some cloud cover may inhibit full radiational cooling. The cloud cover would be noted due to an approaching shortwave trough scraping from the Lower Midwest to the Northeastern Gulf of Mexico. This feature will guide a reinforcing front through the area on Saturday. Limited moisture is expected to mean the front crosses with little more than a passing batch of clouds. Forecast models show a light shower over the Atchafalaya Basin and near the coast, and for that reason we won’t “turn our back” to this one and leave an isolated 10% mention on forecast boards. Broad surface high pressure will become reestablished in the Central U.S. on Sunday continuing the extended cool, dry, tranquil stretch of weather. Persistent northerly winds will continue to hold thermometers at or below average. By Mardi Gras another front and very deep trough will impact the Eastern U.S. with a very cold air mass. It looks as though the deepest pool of cool air will be shunted just northeast of the local area meaning temperatures shouldn’t be much cooler than anything already experienced this winter.
