Tuesday 4-17 morning weather
Continued sunshine and shifting winds will allow further warming on Tuesday and Wednesday. The next cold front will bring only subtle changes into Thursday.
Today and Tonight: Full sunshine and southwest winds of 10mph will bring afternoon highs into the upper 70s and low 80s. Overnight will remain clear with morning lows bottoming out around 60 degrees.
Up Next: More sun is ahead for Wednesday with more warmth. A weak cold front will move through the area on Wednesday night, but at this time, little more than a few extra clouds is expected. Sun and a few clouds will be featured in skies to round out the week. The next storm system to affect the area is pegged for the upcoming weekend. Current expectations are that a cold front will bring showers and storms on Sunday. About a week out, some timing adjustments may be needed as we get closer.
NEW: After further investigation and collecting more data, the National Weather Service has reclassified four local wind damage reports from last Saturday as EF0 tornadoes. The twisters occurred in East Baton Rouge, St. Helena and Tangipahoa Parishes. Below, see the unedited statements from each event.

A weak ridge will move across the area with an associated surface high pressure on Tuesday. The combination will bring subsidence and surface divergence to allow all clear skies and much warmer temperatures. The next 500mb trough will move from west opt east but stay north of the area Wednesday into Thursday. As a result, a cold front will approach the area on Wednesday night, but with little to no upper level support and minimal moisture return from the Gulf of Mexico, showers are not expected. Temperatures may come back below average by 3-5 degrees beyond the boundary but it will still feel like spring out there unlike the past weekend. A sharper and more southern shortwave trough will move out of the Southwest, across Texas and into the local area by Sunday. Return flow entering the weekend will lead to enough moisture for that cold front to produce rain and thunderstorms. While this seems to be likely, it is too early for any details or confidence in severe weather or heavy rain.
