Dreary and chilly again
Akin to last week, cloudy, chilly and damp conditions will prevail through at least Friday Morning.
Today and Tonight: Thursday marks the return of cloud cover and rain showers. Steadier and heavier rain is expected to develop by the afternoon hours. It would be a good idea to carry along an umbrella with you today and evening commuters should anticipate a slower ride home from work. As far as temperatures go, the clouds and showers will really burden the thermal rise leaving many locations in the upper 50s for highs. Overnight, periodic rain will taper to scattered showers. All the while, a cloud deck will hold lows in the low to mid 40s.

Looking Ahead: Moving through Friday, shower activity will wrap up with overcast skies potentially giving way to a few late afternoon peeks of sun. Highs though, will struggle to eclipse 50°. With continued clearing and the region beneath the influence of a cooling northerly breeze, low temperatures will bottom out at, or just above, freezing on Saturday Morning. A mainly clear weekend is ahead with Saturday highs in the mid 50s, Sunday lows in the mid 30s, followed by afternoon highs right around average-62°.
Forecast Discussion: An area of low pressure system will advance from South Texas to the Florida Panhandle through Friday. Bringing along a more saturated atmosphere, the storm system will produce respectable rain totals around Southeastern Louisiana. As mid-level vorticity maxima and the strongest omega (uplift) parameters are expected on Thursday Afternoon, so too are the steadiest periods of rain. While the atmosphere is expected to remain saturated through Friday Morning, most of the surface and upper level support will slide east. Plus, a dry slot entering the mid-levels will cap off deep moisture and any efficient rain-making processes. Continued low-level saturation and a strong inversion (temperature warming with height) will make it difficult for a stratus deck to erode on Friday. Clearing, if at all, will only partially occur late in the day.
By Saturday Morning, a surface high pressure system building into Texas will increase the drier, northerly winds and should thoroughly clear our skies of clouds. In fact, several reinforcing fronts with cool, dry air will provide sunny and seasonable afternoons right into the middle of next week.
