NWS Little Rock, AR wrote its last area forecast discussion before the first event at Apr 26, 5:42 AM CST, 2 hours 48 minutes earlier.
Area Forecast Discussion National Weather Service Little Rock AR 642 AM CDT Mon Apr 26 2021 .AVIATION... High pressure will move off to the east and the pressure gradient will increase as low pressure moves into the Plains this afternoon. Gusty winds are expected today. High clouds will continue over the area and some wind shear is expected in the north. Patchy MVFR conditions are possible in the morning, otherwise VFR conditions will continue. && .PREV DISCUSSION...(ISSUED 345 AM CDT Mon Apr 26 2021) SHORT TERM...Today Through Tuesday Night A large upper ridge is over the center part of the country this morning and will continue to move east. This upper ridge will be centered over the east coast Tuesday with southwest flow returning to Arkansas. An upper low over the west Tuesday will move into the desert southwest Tuesday night. Surface high pressure is east of Arkansas this morning and will keep winds out of the south today with gusts at times. High clouds will increase as they come over the upper ridge but abundant sunshine is still expected. A short wave in conjunction with increasing moisture advection will bring a chance of showers to the west Tuesday afternoon and these will spread eastward Tuesday night. Highs today will be in the upper 70s to mid 80s and Tuesday will be in the mid 70s to mid 80s. Lows tonight will be in the upper 50s to lower 60s and Tuesday night lows will be warmer in the mid to upper 60s. LONG TERM...Wednesday Through Sunday An upper level closed low will be over the SRN Rockies at the start of the long term period...with AR under SW flow aloft downstream of this upper trough. This setup will allow for moisture levels to increase across the region. This upper low will slowly drop SE over AR by late Thu into early Fri...weakening into an open trough as it moves across the state. As this happens...a slow moving cold front will drop SE into the state...with upper level disturbances lifting NE over this front ahead of the trough. This setup will bring several rounds of SHRA and some TSRA in vicinity of this slowly moving front...with potential for several inches of rainfall increasing for portions of the region. Latest data keeps the bulk of the SHRA/TSRA across the far NWRN portion of the CWA on Wed into Wed night...and areas to the NW. As the front drops further SE late Wed night into Thu...the axis of widespread rainfall will drop SE across a larger portion of the CWA. By Thu night into early Fri...this front will drop SE of the state...with chances for SHRA/TSRA decreasing from NW to SE during the day on Fri. Beyond Fri afternoon...NW flow aloft will keep POPs low for much of the rest of the forecast as no appreciable moisture return will be seen over this coming weekend. While it seems model certainty has increased some recently...there remains differences in details regarding the speed of the frontal passage and eventual placement of the axis of heaviest rainfall. The GFS continues as the faster solution...with the ECMWF about 12 hrs slower...but recent trends have shrunken the time differences between the med range guidance. Latest thinking results in a blend of the NBM with some bias towards the ECMWF. This puts the heavy rainfall axis from SRN OK into NERN OK/NWRN AR and SW MO...with rainfall amounts across the NWRN third/half of the CWA of 1.5 to 3 or more inches of rainfall from Tue night through Fri. Some rainfall amounts of 3 to 4 or more inches will be possible further NW across extreme NWRN AR. Due to continued uncertainty in timing and placement of the heaviest rainfall...these numbers could still change over the next few days. Lesser rainfall amounts of 1.5 inches or less is expected across SERN third of the CWA. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...51
Hazardous Weather Outlook National Weather Service Little Rock AR 349 AM CDT Mon Apr 26 2021 ARZ003>008-012>017-021>025-030>034-037>047-052>057-062>069-271000- Boone-Marion-Baxter-Fulton-Sharp-Randolph-Newton-Searcy-Stone- Izard-Independence-Lawrence-Johnson-Pope-Van Buren-Cleburne- Jackson-Logan-Conway-Faulkner-White-Woodruff-Scott-Yell-Perry- Polk-Montgomery-Garland-Saline-Pulaski-Lonoke-Prairie-Monroe-Pike- Clark-Hot Spring-Grant-Jefferson-Arkansas-Dallas-Cleveland- Lincoln-Desha-Ouachita-Calhoun-Bradley-Drew- 349 AM CDT Mon Apr 26 2021 This Hazardous Weather Outlook is for a Large Part of Arkansas. .DAY ONE...This Afternoon and Tonight No hazardous weather is expected at this time. .DAYS TWO THROUGH SEVEN...Monday Through Saturday Showers and thunderstorms return to the forecast Tuesday through Friday...with several rounds of rainfall possible. Some areas could see heavy rainfall as a result for the middle to the latter part of this week. However...the areas expected to see the heaviest rainfall remain uncertain at this time...but latest data suggests the northwest half to third of the state will see the heaviest rainfall. Rainfall amounts of two to four inches possible across the northwest third of the area...with lesser amounts to the southeast. This may result in an increased threat for flash flooding for these areas. Uncertainty remains regarding the potential for strong thunderstorms...depending on when this storm system pushes closer to Arkansas during the latter half of the week. For now...the overall threat for seeing organized severe weather remains low for much of the forecast. Refer to the latest forecasts in the coming days as uncertainty regarding the potential for heavy rainfall and possible strong/severe thunderstorms becomes more clear over time. .Spotter Information Statement... Spotter activation will not be needed. && Visit NWS Little Rock on the web. Go to http://weather.gov/lzk. 51/62
