Area Forecast Discussion National Weather Service New Orleans LA 330am CST Wednesday Jan 29 2020 A shortwave that dropped out of the Rockies is passing through the Central Plains early this morning and headed across the lower Mississippi Valley today. POPS are at the peak of this event right now, with most of the CWA seeing periods of light to moderate rain. The few thunderstorms that do exist have been south of New Orleans. Quantitative Precipitation Forecast totals are not expected to be very high, generally around 1/4" or less. The back side of the main rain shield should be east of I- 55 by daybreak and east of PQL by noon. Sporadic lingering light showers will be possible through a good portion of the day. Weak cold air advection on the backside of the shortwave will bring down temps a few degrees on Thursday. The progressive upper level pattern thats been bringing rain to the area every 2 to 3 days looks like it will persist through the rest of the week. Models show a trough more amplified than any previous others to move across the Mississippi Valley Friday night. Southward digging of the base of the trough will reach into the western Gulf of Mexico off the TX coast Friday. This will bring a wide swath of showers across at least the southern half of the forecast area. Once it moves east of the CWA Friday night, finally should see at least a few consecutive dry days before the next system moves in. This may not be until late Monday into Tuesday. Marine A fast moving surface low and frontal boundary will move through today. SE winds today of 20 to 25kt will shift to west around 20-25kt after the cold front moves through. Winds will then become northerly and ease to 10-15kt Wednesday night into Thursday. A small craft advisory will be posted today but will be rather short lived. Another cold front will begin to affect the area by the end of the week with east winds Thursday night around 15kt becoming southerly Friday and shifting to north around 20kt late Friday through Saturday. Winds will ease Saturday night and become more NW into the new week with high pressure settling into the north central gulf. NOAA New Orleans LA Office: Watches - Warnings - Advisories LA...None.
