Late afternoon through tonight: The upper low that is responsible for the past few days of wet weather is now beginning to make a move northeast, and we are seeing the shower/thunderstorm development become a little more confined and diurnal in nature.
Fog is expected to develop again late tonight into early Tuesday morning, but the threat for dense fog appears to be less. /EC/

Tuesday through Sunday: The mid/upper level low pressure system responsible for the rain and storms across the forecast area the past few days, will lift northeast of the region Tuesday into Wednesday. Before it exits, this weakness will again result in scattered to numerous showers, along with a few thunderstorms, across mainly the Golden Triangle area Tuesday afternoon. This activity will dissipate in the late afternoon, as heating wanes and the low lifts further northeast and out of the region.
Otherwise, look for highs Tuesday afternoon from the mid 70s to mid 80s, with lows Tuesday night from the middle 60s to around 70.

Ridging aloft and high pressure at the surface will setup across the region Wednesday into Thursday. This will result in a return to quieter conditions, but with increasing temperatures. On Friday, the ridge will begin flattening, with quasi-zonal flow prevailing across the CWA through the weekend. It'll be during this Friday through Sunday timeframe, that a couple of disturbances aloft are advertised to affect the region. These disturbances, combined with the expected unstable airmass that'll be present across the region, in addition to some flow, could yield some potential for a complex of storms or two, possibly affecting portions of the CWA Again, this will be in the Friday through Sunday timeframe. This is still several days out. Please continue to monitor the latest forecast for the most up-to-date information.

As eluded to above, temperatures will be on the rise areawide under the influence of the aforementioned ridge and high pressure. Highs will steadily warm through mid-week, with low to mid 90s expected nearly areawide come Thursday, with lows struggling to fall out of the 70s. The upper 80s to lower 90s will continue each afternoon heading into the weekend. However with the increased rain chances around each afternoon, convection, and outflow and clouds associated with it, will likely keep highs slightly less than what they could potentially reach. /19/
