A quick update was issued this evening to account for recent trends in hi-res models with a slight chance of thunderstorms overnight. Otherwise, there are no major changes to the forecast. At the mid-levels, a broad ridge is centered across much of the CONUS with high pressure centered over the central Plains into the Intermountain West. A few isolated showers and thunderstorms are lingering over southwestern Arkansas and the ArkLaMiss this evening with IR satellite imagery indicating clouds spilling off of earlier convection westward across much of the ArkLaTex.
Tonight, showers and thunderstorms will mostly diminish across the area with the continued loss of heating. The humid atmospheric conditions tonight are well-represented by dew points in the upper 70s to around 80 across much of the area with the exception being localized drier air in the Shreveport-Bossier metro with dew points in the lower 70s. It appears that there will be enough instability maintained overnight across the area for a few isolated showers and thunderstorms over the ArkLaTex. The 18Z NAM 3km and recent hourly runs of the HRRR are hinting at this. Other hi-res models indicate showers and thunderstorms completely diminishing. Did not want to completely discount the HRRR/NAM given the warm dew points and thus have a slight chance of showers and thunderstorms to account for this possibility overnight.
For temperatures, a warm and humid night is expected with lows close to NBM guidance ranging from the mid to upper 70s across the area. Temp trends continue to favor another hot and humid day tomorrow with heat indices in to 105 to 110 range. Thus, the Heat Advisory remains in effect for Tuesday afternoon. /04-Woodrum/
