NWS Little Rock, AR wrote its last area forecast discussion before the first event at Jun 11, 4:56 PM CST, 3 hours 21 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service Little Rock AR 556 PM CDT Fri Jun 11 2021 .DISCUSSION... Updated to include the 00Z aviation discussion below... && .AVIATION... VFR conditions are ongoing early this Fri evening...which should remain dominant for most terminals overnight and through Sat. However...some patchy fog may be seen at central/SRN terminals near sunrise. A TSRA cluster in MO/KS early this evening may remain intact this evening into the early overnight period...which could impact the NRN terminals. Have mentioned VCTS and tempo TSRA at these terminals late this evening and just after midnight for this potential. && .PREV DISCUSSION...(ISSUED 251 PM CDT Fri Jun 11 2021) SHORT TERM...Tonight Through Sunday Long story short - hot and humid conditions are going to continue thru the short term as a ridge builds to the west of us. A N to NW flow aloft will persist, and it certainly looks like an MCS may form upstream of the forecast area tonight. There are some uncertainties as to exactly where it may form, and where it may move, but with the flow pattern the way it is, portions of northern AR could certainly end up under the downstream remnants of any MCS development. Additional thunderstorms may pop up just about anywhere during the afternoon hours tomorrow, although the presence of any old outflow boundaries may serve as a focal point for convection. By Sunday, afternoon convection will likely be limited to the southeast quarter of the state. Heat index values will be getting up pretty close to advisory criteria in some areas this weekend, but I anticipate that they will fall just a bit short of criteria. LONG TERM...Sunday Night Through Thursday The period begins with high pressure building in creating a summer- like pattern through the middle of next week. Temperatures are expected to be above normal across the CWA. Highs looks to be in the upper 80s to low 90s with lows in the upper 60s to low 70s. This summer-like pattern and a building ridge will lead to low PoP chances through the period. With that said, confidence is not very high on PoPs. Current forecast tends to lean more on model guidance because of timing being in long term with model guidance being less enthusiastic about rain potential through late next week. However, it would not be a surprise to see some summertime convection during any of these days, especially late in the period. && .LZK Watches/Warnings/Advisories...NONE. && Aviation...62
Hazardous Weather Outlook National Weather Service Little Rock AR 411 AM CDT Fri Jun 11 2021 ARZ003>008-012>017-021>025-030>034-037>047-052>057-062>069-120915- 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- 411 AM CDT Fri Jun 11 2021 This Hazardous Weather Outlook is for a Large Part of Arkansas. .DAY ONE...Today and Tonight Patchy fog is expected this morning. A few places could see dense fog reducing visibility. Isolated to scatterd showers and thunderstorms will develop mainly this afternoon and evening. An isolated storm or two could become strong to severe, with gusty winds the primary hazard. Given excessive rainfall over the last several days and an extremely saturated soil surface, it will not take much runoff from heavy rainfall to quickly cause flash flooding. Where rainfall accumulations are the greatest, flash flooding may be considerable to significant in nature at times. Please be sure to heed local emergency management guidance on road closures due to high water, and avoid flooded areas if possible. .DAYS TWO THROUGH SEVEN...Friday Through Wednesday A weather pattern more typical of summer will develop over the region heading into the weekend as a large upper level ridge of high pressure builds over the nations mid section. Hot and humid conditions will return with chances of afternoon through early evening showers and thunderstorms. An occasional strong storm can not be discounted but organized severe weather is not likely. Highs are expected to top out in the upper 80s to mid 90s through Tuesday before some slightly cooler air moves in. With the soil being saturated and lots of standing water likely, very muggy conditions are expected as well. Heat index values will approach the century mark across parts of the state this weekend. .Spotter Information Statement... Spotter Activation May Be Needed. && Visit NWS Little Rock on the web.
