UPDATE. For 12Z Aviation.
SHORT TERM. /Updated at 0300 AM CDT Sat Jun 12 2021/
We are finally watching the trough begin to work out of the area, as a a ridge build in. With that said though a surface trough will be sliding through the area. This combined with afternoon heating with likely result in fairly large CAPE within the column. With descent lift, 20 to 30 kt effective shear and localized enhancements with numerous boundaries in place, this large CAPE will likely result in multicellular storms that will result in strong to severe storms this afternoon with wind being the main threat along with large hail at times. We will also need to watch any training storms as they move over a very saturated ground from the past week. Look for the stronger activity to work through at least 9 PM and could potentially last a touch longer but more isolated in nature. Showers and embedded storms will continue into the evening but will be slide south and could be south of the area by Midnight.
As we move into Sunday the better moisture will be across the south and southwest, so went with the higher PoPs here. With that said it will be more like your typical summertime pattern here as the best focus will be south of the area. Activity should begin to dwindle down as we approach the send of the daytime hours on Sunday. Highs will be a touch warmer on Sunday as the sun will be around a little longer. Look for upper 80s to low 90s today with low 90s on Sunday.
LONG TERM. /Updated at 0300 AM CDT Sat Jun 12 2021/
Monday through Friday.
Guidance is in general agreement and suggestive of a very prominent deep-layer ridge establishing across the Intermountain West early/mid next week (could approach ~600 dam at H5 Tue-Thu which is impressive). The corresponding amplification of the upper-level jet stream will result in a longwave trough to position across the East Coast northeastward into Quebec where the parent upper-low will reside. Across the Deep South and Gulf Coast, a residual upper-level weakness will meander along the northern Gulf and should generally stretch northeastward toward the Carolina Coast on Monday. Northerly flow will encompass much of the area by then, so tropospheric moisture content will be in a state of decline. PoPs will therefore favor areas southward where best PWs are expected (1.4"-1.6"). This should foster isolated/scattered showers and thunderstorms mainly during peak diurnal heating. This will also describe the overall theme for Tuesday, though rain chances decrease each day through Thursday as drier air further invades the Deep South. This is despite shortwave perturbations rotating into the area from the north around the base of the longwave trough. Uppers 80s & lower 90s will be the expected highs through Thursday afternoon unless convection sees otherwise. The forecast becomes a little more complicated later in the period as unsettled weather is forecast across the Gulf of Mexico late next week. The NHC is monitoring for potential tropical cyclone development near the Bay of Campeche during this time frame. However, general storminess could encompass the Gulf Coast due to rich tropical moisture slowly creeping northward. PoPs were increased as a result, though forecast confidence remains low at this time.
AVIATION. 12Z TAF Discussion.
West-northwesterly flow aloft, once again is producing early morning showers and few storms. Skies are starting out MVFR/IFR once again this morning. Coverage increasing during the day with numerous showers and storms in the afternoon and early evening. Activity will diminish between 4 and 7z.
Note: AMD NOT SKED until further notice at KASN due to ongoing equipment issues.
Relative humidity values remain elevated today with scattered to numerous showers and thunderstorms by this afternoon and evening. Some thunderstorms could be strong to severe. Otherwise, northwesterly 20 ft winds of 5-10 mph are expected. Winds should trend more northerly by Sunday. This will begin a period of decreasing moisture which will result in lower rain chances and lower afternoon RH values (40-50%) into next week.
