Issued at 300 PM CDT Thu Apr 25 2024 Scattered showers and isolated thunderstorms will be possible this evening, mainly to the north of Memphis ahead of a slow moving warm front. After the warm front moves north of the Mid- South, warmer and more humid conditions will spread into the region on Friday and continue through the weekend. Scattered showers and thunderstorms are expected over eastern Arkansas and the Missouri bootheel for Friday and Saturday. Thunderstorms will become more widespread across the entire Midsouth Sunday night through Tuesday, as a Pacific cold front approaches the region. && .DISCUSSION... (This evening through next Wednesday) Issued at 300 PM CDT Thu Apr 25 2024 Skies are cloudy across southern sections of the Mid-South with mostly sunny skies over the remainder of the region. Temperatures this afternoon are in the 60s to around 70 degrees. A large area of showers cover much of east Arkansas, southwest Tennessee and north Mississippi. All of this activity is north of slow moving warm front which extends across extreme southern Arkansas and into central Mississippi. As the warm front lifts north into north Mississippi tonight, the area of showers and isolated thunderstorms will move north into northeast Arkansas and west Tennessee. Temperatures will remain near normal tonight with lows from the mid 50s to lower 60s. On Friday, the warm front continues to move north into the Mid- Mississippi Valley, bringing an end to the threat of rain for areas east of the Mississippi River. Behind the warm front, warmer and more humid air moves into the region. Temperatures will be some 10 to 15 degrees warmer than today with highs in the low to mid 80s. A frontal boundary will stall out across the central and southern Plains by Friday evening. Thunderstorms are expected to form ahead of the front with some the activity reaching areas of the Mid-South west of the Mississippi River for Friday night and Saturday. Most areas should see dry weather for Saturday night through Sunday morning as the thunderstorms that develop over the southern Plains on Saturday are not expected to reach the Mid- South. By Sunday, the cold front will begin to move slowly east reaching western Arkansas by Monday and into the Mid-South on Tuesday. As the front gets closer to the region, showers and thunderstorms will increase in coverage from west to east. Rainfall could become heavy across portions of the Mid-South west of the Mississippi River for Sunday night into Monday. Any threat of severe weather should be confined to areas west of the Mid-South across central and western Arkansas. With extensive cloud cover and rain expected on Monday, temperatures will be cooler. Once the cold front moves through the region, dry weather is expected for Tuesday night. Warmer weather returns to the region for Wednesday with a few thunderstorms possible ahead of an upper level disturbance. && .AVIATION... (00Z TAFS) Issued at 657 PM CDT Thu Apr 25 2024 As a warm front continues to lift north over the airspace, a swath of showers will intermittently affect MKL and JBR over the next few hours. Ceilings along this boundary are around 5 kft AGL and no lightning is expected so aviation impacts will be minimal. A cold front will approach tomorrow, increasing southerly winds to 10-15 kts with gusts approaching 25-30 kts. Another round of precip is expected late in the period after 00Z Saturday, though the thunder potential is a bit more uncertain given the trend toward less instability at the diurnal minimum. A midlevel cloud deck between 5-10 kft looks to persist through the period areawide. CAD && .MEG WATCHES/WARNINGS/ADVISORIES... AR...None. MO...None. MS...None.
