Still seeing some of this ongoing across the lower Toledo Bend Country with KSHV VWP showing 30kts at 1-2kft helping to sustain this convection along a residual outflow boundary from earlier convection across Deep East Texas. This higher pwat airmass should push northward across our region today and thus, expecting an uptick in convective coverage due to upstream perturbations embedded in WSW flow aloft headed our way from the west.
Weak upper ridging builds in Wednesday evening into Thursday morning, then an upper trough will approach from the west resulting in a chance for showers and isolated storms along and west of the Cascades. Given the upper pattern with the upper trough still offshore Thursday afternoon typically results in increasing instability east of the upper low. Additionally, the HREF calibrated thunderstorms also shows the highest vales along and west of the Cascades mid to late Thursday afternoon, with storms shifting over the Cascades Thursday evening.
Any lingering fog or low stratus lifts after daybreak allowing for ample daytime heating across the area bringing highs into the lower to middle 80's once again.

Our next weather system will arrive over the weekend, bringing gusty winds and cooler than normal temperatures to the region. In addition to slightly cooler temperatures, we will also see breezy southerly-to-southwesterly winds pick up across area today and tomorrow with the strongest of these winds occurring in the western Mojave Desert where 30 to 40 mph wind gusts are expected.
The tornado risk is low, given the weak, unidirectional flow in the low levels.
Expect showers to develop this afternoon over the higher terrain near the Nevada border when surface heating peaks.
Winds become breezy to windy this weekend, arriving with cooler temperatures as a system moves to the north. Over the coming days flow aloft over southeastern Arizona will tighten and become more southwesterly while an eastern Pacific trough deepens and approaches. This trough is forecast to lift northeast into the Great Basin through this weekend, with southeastern Arizona under the dry southern periphery. This leaves the area with dry and breezy to windy conditions in the forecast with cooler temperatures arriving this weekend.
But can't rule out an isolated strong storm to develop as the environment supports elevated storm development north of the front where storms could sustain themselves as there is sufficient moisture north of the front with sfc dew points in the 30s and 40s, with marginal moisture at 850mb, but moisture starts to decrease in the lower levels the farther north of a line generally along I-80 through the afternoon hours. As far as temperatures tomorrow, cooler temperatures will be expected with overcast skies and widespread rain showers continuing through the day.
Ample moisture in the low-levels and saturated soils will enable more patchy fog development tonight with highest probabilities across the Florida Parishes and Southwest MS, particularly between Baton Rouge and McComb.
