000 FXUS64 KMEG 150428 AFDMEG Area Forecast Discussion National Weather Service Memphis TN 1128 PM CDT Sun Apr 14 2024 ...New AVIATION... .UPDATE... Issued at 914 PM CDT Sun Apr 14 2024 Skies are mostly clear across the Mid-South this evening with temperatures in the low to mid 70s. Another dry and warm night is in store across the region as high pressure remains over the eastern Gulf of Mexico. Temperatures will remain above normal overnight with lows Monday morning in the upper 50s to lower 60s. Will update forecast to remove evening wording. ARS && .SYNOPSIS... Issued at 330 PM CDT Sun Apr 14 2024 A ridge of high pressure will bring a continuation of dry weather to the Mid-South through Tuesday morning. Lows tonight and Monday night will be in the upper 50s to 60s with highs on Monday in the upper 70s to lower 80s. Shower and thunderstorm chances will increase Tuesday afternoon into Wednesday as a cold front moves through the region. A few strong to severe thunderstorms will be possible. Additional rain chances along with cooler air are possible towards next weekend. && .DISCUSSION... (This evening through next Saturday) Issued at 330 PM CDT Sun Apr 14 2024 GOES-16 Satellite trends show a subtle and weak mid-level trough moving through the Lower Mississippi Valley. This upper-level feature only produced a few mid/high level clouds due to a ridge of high pressure being present in portions of the Southeast United States and the Gulf of Mexico. Temperatures have warmed into the upper 70s to lower 60s this afternoon. Ample mixing and a low-level jet present across the region has allowed the warmer temperatures and elevated winds to mix to the surface. Dry weather is expected to continue through Monday evening as shortwave ridging remains in place across the region. Winds are expected to decrease tonight as the low-level jet weakens across the area. Temperatures will continue to be mild with highs on Monday in the upper 70s to lower 80s with lows Monday night in the 60s. Short-term model soundings and HREF guidance indicates a potential for the increasing low-level moisture to produce some stratus late tonight into Monday morning, especially south of I-40. An upper-level low over California is expected to push east into the Central Plains on Monday and into the Upper Midwest by Tuesday night. A tightening pressure gradient associated with an accompanying surface low and the development of another low-level jet will result in increased winds across the area Tuesday into Wednesday. A Wind Advisory may be needed for Tuesday into Tuesday night if NBM winds are correct with the low-level wind fields. Shower and thunderstorm chances are expected to increase across the region later Tuesday afternoon into Tuesday night as an accompanying cold front slowly moves into the Mid-South. Current short-term trends suggest the convective environment will be a low CAPE/high shear environment characterized by LREF Ensemble guidance showing surface-based CAPE values between 400-800 J/kg and 0-6 km shear in excess of 50 kts. Additionally, model soundings show some slight curvature in the hodographs to produce some sufficient helicity. This may be enough for at least a few strong to severe thunderstorms Tuesday night with damaging winds as the main threat and perhaps a tornado in this conditional environment. Instability is expected to be better on Wednesday as the front continues to slowly move through the region. A few strong to severe thunderstorms will be possible with shear will be somewhat less and better upper-level support being displaced away from the region. Long-term model trends show another cold front dropping south into the region for next weekend. This next system will bring additional rain chances along with a drop in temperatures to the Mid-South.
