Back
to an urbanized area with Dallas/Fort Worth airport (KDFW). Thick mid to
upper-level clouds are already in place and low clouds will develop late in the
night, as often occurs with a moist south-southeasterly flow off the Gulf of
Mexico transporting moisture into the boundary layer that cools at night to
saturation. The wind and clouds will limit radiational cooling regardless of the
urban heat island effect, and actually, the Dallas area is unlikely to be much
warmer than the surrounding area. During the day tomorrow, low clouds could
slowly break up but will be widespread enough to prevent a quick warmup, with
winds strengthening slightly given the modest daytime heating allowing for
mixing of stronger winds from aloft, especially during any break in the clouds.
Rainfall is very uncertain, with showers and thunderstorms possibly just
reaching KDFW but could also just miss to the northwest. Perhaps there will be
some scattered storms producing light rainfall amounts. I don’t think the
hotter models will verify given the storms in proximity, but they could if the
storms stay a little farther northwest.
