Coolest temperatures since Late May on the way

A cold front has moved through the area. Humidity is falling and thus seasonably warm afternoons won’t feel as steamy. Morning temperatures will be able to drop into what some might consider “cool territory.”

THE FORECAST:

Today and Tonight: For Tuesday, some lingering cloud cover may be anticipated as your friendly neighborhood cold front continues a slow crawl into the Gulf of Mexico. Closer to the coast, enough moisture and lift may remain to produce a straggling shower. Humidity will continue to fall and high temperatures won’t exceed the mid to upper 80s. Overnight, skies will go clear with lows in the mid 60s. Baton Rouge has not experienced a low temperature at or below 65 degrees since May 24. The WBRZ Weather Team is projecting 64 degrees for the Capital City. 

Up Next: The remainder of the week and the weekend will be nothing if not pleasant. Skies will remain mostly clear with high temperatures in the mid 80s and low temperatures in the low 60s or even upper 50s! As northerly winds continue to reinforce the cooler temperatures, it is not out of the question that Friday’s high fails to leave the 70s in some cooler northern neighborhoods. Average highs and lows this time of year are around 85/64, so welcome alas some normalcy.   

The Tropics: We are watching a system in the Central Atlantic that is expected to become Tropical Storm Matthew. Gusty wind and rain will move through the Windward Islands and Southern Lesser Antilles before the storm moves into the Caribbean Sea. In very warm waters, this storm has some potential and begs watching, but that is all for now. You are likely to see and hear much chatter about this system, not all will be fully reliable.

THE SCIENCE:

Forecast Discussion: A cold front will be driven through the area as an upper level trough moves into the Great Lakes region today. As the frontal slowly chugs by, some lingering cloud cover is possible—even a stray shower in coastal areas. Behind this front, much drier air noted by dew points in the low 60s and upper 50s will bring some of the most comfortable temperatures since spring. The cooler and drier air mass should be fully in place by Wednesday. As the upper trough digs even further into the Eastern United States, and a surface high pressure system sets up west of the trough, continued northerly winds and the associated continental air mass will keep low temperatures a few degrees below average heading into the weekend. A secondary reinforcing front will likely cross the area on Thursday. With mainly clear skies, pleasant outdoor weather is expected through Sunday and dare I say a light jacket may be desired on Friday and Saturday Mornings. Looking longer term… if this same trough stays sin place (and long range models are not budging it), the tropical wave moving toward the Caribbean Sea could be snared and sent northward away from the U.S. but time will tell on that.
