Dry, milder through Halloween
Monday and Halloween will remain sunny, but some showers return to the forecast midweek. The chill will get out of here for the week ahead.
Today and Tonight: Your new week starts on a chilly note, but ample sunshine and a wind shift to the south will allow high temperatures to climb into the mid 70s. Overnight will be clear and cool, but about 10 degrees warmer than the previous morning. Expect low temperatures in the low 50s.
Up Next: By Wednesday, we will see some more clouds across the area and the chance for showers and thunderstorms. A disturbance will move through on Thursday and that will enhance rain coverage. Temperatures will be much warmer than they are now. In fact, we'll likely be back in the 80s as soon as Thursday in some areas. To put that in perspective, last Saturday's high temperature will be Wednesday's low temperature. Into the weekend, the forecast is trending drier. While some more humidity comes into the area, it will not be excessively humid like the summer season.
The Tropics: Tropical Storm Philippe quickly pulsed and dissipated in the southwest Atlantic Ocean over the weekend. A non-tropical low in the north central Atlantic could develop slowly this week as it drifts in the open waters and poses no threat to land.
Light southerly winds will begin a very slow return of moisture to begin the week. At first, the only response will be a slight gain by thermometers on Monday and Monday night. Given the slow return of moisture, it would not be a surprise to see some fog development over the next couple of nights. A slow-moving front will approach on Tuesday and then stall well away from the local area. This front will draw even more moisture northward and this will interact with a trough in the jet stream to cause lift and rain development through Friday. A few embedded waves of energy may enhance activity at times. Rain coverage and amounts will be highest for areas north and west of Baton Rouge and lowest south and east. An area of high pressure will overtake the region this weekend eventually lowering rain chances.
