Area Forecast Discussion National Weather Service Shreveport LA 229 PM CDT Sun Apr 5 2020

SHORT TERM. /Tonight through Monday Night/

Upper ridge axis continues to bisect the CONUS and our region ahead of a cut-off low just off the coast of nrn CA. High pressure remains in place at the sfc. Weak swly flow across the wrn half of our region has resulted in enough lift to keep clouds in place. We may see some decrease in cloud cover this evening as the upper ridge amplifies a bit, but this will be short-lived. Clouds will again begin to increase towards sunrise Monday, as the ridge axis shifts ewd. Overnight min temps should be a bit milder than previous nights as the combination of warmer daytime temps and insulating cloud cover hold them up.

Chances for shwrs and a few tstms will return to the fcst by Monday aftn, as lift increases in swly flow aloft. Peeks of sun and returning sly flow at the sfc will aid temps in reaching into the mid 70s to near 80 degrees, adding enough instability to get a few rumbles of thunder with any convection. Widespread cloud cover Monday night will hold temps up in the 60s at most sites, well above early April normals. /12/ LONG TERM. /Tuesday through Sunday/

Warm air advection will be ongoing across the region through mid week as southerly flow prevails. Weak perturbations in the W/SW flow aloft will bring continued rain chances on Tuesday, then decreasing on Tuesday night through Wednesday as weak upper ridging stretches in from the west. During this timeframe, temperatures will run well above normal with highs ranging through the 80s on both Tuesday and Wednesday while overnight lows will mainly run in the 60s.

By Wednesday night into Thursday, a cold front will advance its way southward across the region and increase our rain chances once again with additional upper level support from an emerging trough from the Rockies across the Southern Plains. At this point in the forecast, details become a bit murky as model solutions greatly diverge on resolving the evolution and track of this upper level trough. The GFS is much more progressive with the trough and ushers it east on Friday through Friday night before exiting the region by Saturday morning. Meanwhile, the ECMWF solution is more ominous with a slower and more southerly track which portends a potential for some severe weather by late Friday through Saturday. Given these discrepancies, will continue to carry PoPs into the first half of next weekend with still a fair amount of uncertainty in the forecast beyond the middle of next week. /19/

PREV DISCUSSION. /issued 107 PM CDT Sun Apr 5 2020/

AVIATION .

A mix of MVFR/VFR conditions will prevail this aftn, as some portions of the region experience some peeks of sun today. Cigs will lower again late tonight towards sunrise Monday, especially across E TX terminals. Otherwise, expect light and vrbl winds to continue throughout the pd. /12/

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
