NEW ORLEANS, LA (WVUE) - It's been a spectacular Sunday with chilly morning lows and pleasant afternoon highs, but the nice weather is coming to an end. Clouds increase throughout the evening and we are preparing for wet weather to take over for the upcoming week. The high pressure that kept us nice the last couple of days is now well east and we are experiencing a surface flow out of the southeast bringing in warm, moist air. This is rapidly increasing moisture throughout the area.
The upper level flow is changing as well. We are now seeing a southwest flow on the leading edge of a deep trough draped across the southwest. Several disturbances will circulate around the base of this trough to bring us a very wet forecast this Christmas week. Look for a few showers early on Monday with the heavier rain moving in Monday afternoon and sticking around for several days. The Storm Prediction Center places us under a marginal risk for severe storms late Monday and Tuesday. This does appear to be mostly a rain event with the opportunity for 3 to 5 inches of rainfall to accumulate in some areas over the course of the week.
The heaviest rain should back off by Wednesday, but we will still have scattered showers in the forecast for Christmas Eve and Christmas Day. With plenty of moisture around and warm temperatures Rudolph may be needed for Santa's flight as rain and foggy conditions are both possible. Stick with Fox 8 as we get closer to the holidays.
