Similar to Wednesday, the Baton Rouge area will have a freezing morning become a sunny afternoon.


Today and Tonight: Your Thursday will again feature plentiful sunshine with high temperatures topping out in the mid 50s. During the evening hours, high clouds will quickly thicken as winds shift from north to southeasterly. This makes the low temperature forecast difficult as the wind shift will dictate exactly when overnight cooling ends. A freeze is not expected, so we'll forecast lows in the upper 30s after midnight before a bit of warming occurs prior to dawn.

Looking Ahead: On Friday, the region will start to notice effects from a warm front lifting north. A mostly cloudy day can be expected with a couple of showers as well. On the flip side, temperatures will quickly climb through the 40s and 50s into the mid 60s. Friday Night will be much milder with spotty showers and lows in the mid 50s. Your weekend doesn't appear to be a total washout, but keep in touch with us for radar updates as there will certainly be some showers to dodge. Saturday will be breezy and even warmer with highs in the 70s despite mostly cloudy skies and scattered showers. We anticipate similar temperatures on Sunday with more clouds, showers and wind. A cold front will sweep through Sunday Night with falling temperatures into Monday as well as lingering showers.

Forecast Discussion: High pressure over the Upper Mississippi River Valley will shift east on Thursday, weakening the northeasterly surface wind flow over the region. As winds take on a southerly component during the overnight hours, moisture will return quickly and a cloud deck will begin to develop. Low temperatures will respond to both phenomena-likely bottoming out early and then remaining steady or rising prior to dawn. It is difficult to pin down exactly when this will occur but as no freeze is expected and no significant impacts are expected from whatever the low may be, we will comfortably issue a forecast low in the upper 30s. On Friday, an upper-level wave over the Southwest U.S. will kick a warm front northward through Louisiana. With this added forcing and moisture, a mostly cloudy day will occur with some spotty showers also possible. Positioned in the warm sector of a newly developed surface storm in Texas, southerly breezes will prevail through the weekend. With a good deal of moisture in place and a modest omega (uplift) field, there will be no shortage of clouds but forecast model precipitation returns are low. This is because upper level support for shower development is rather unimpressive. Still scattered showers will be possible and chances will increase on Sunday as the storm complex shifts east and drives a cold front into the area. Forecast models also stall the front for a day and leave us under a cloud deck with showers on Monday. With a zonal (west to east) flow aloft, the isn't much push to drive the front south. So, the slower progression makes sense. Both models do have the cooler air arriving by Monday too. If clouds and showers stick, Monday could end up being a very raw day.
