Chances for showers will hold through Monday, though only isolated activity is anticipated. A significant warming trend will get underway this afternoon.

THE FORECAST:

Today and Tonight: On Sunday, as winds shift from east to south at 5-10mph, expect thermometers to push 80 degrees. After clouds in the morning, some sun is expected to break through during the afternoon, with an isolated shower possible later in the day. Overnight, any showers will subside and low temperatures will be a bit stuffier in the upper 60s. 

Up Next:  The first full week of spring is looking warmer and drier than average across the Baton Rouge area and southeast United States. For reference, average temperatures are highs in the mid 70s and lows in the low 50s. While an isolated shower will still be possible on Monday, the rest of the week should feature partly sunny afternoons with high temperatures in the mid to upper 80s. One or two locations could clip 90 degrees. Record high temperatures could fall at Metro Airport Wednesday through Friday. Lows will be in the upper 60s and low 70s.     

THE EXPLANATION:

A warm front along the Gulf Coast will lift north through the area on Sunday afternoon. Onshore flow will commence and as temperatures warm, some scattered, frontal forced shower activity is possible across the northern half of the forecast area. Additional weak impulses in the mid to upper levels may create isolated showers later Sunday through Monday. A warm front will transition north of the area by Monday afternoon establishing southerly surface flow  that will anchor through much of next week. Additionally, a ridge of high pressure aloft will strengthen over the Gulf of Mexico leading to subsidence warming Wednesday through Friday. As a result, dry conditions are anticipated with record warmth likely. Thursday and Friday may even challenge 90 degrees. An upper level trough and associated cold front may attempt to tamp this warmth down by next weekend but that is too far out to project with confidence.
