A fairly strong ridge of high pressure overhead will remain the dominant weather feature this week.  Rain chances for the next several days will be confined mainly to coastal areas driven by the daily seabreeze. This high pressure ridge is not atypical for this time of the year, and David had a great blog about that earlier this afternoon.  If you missed it, check it out here:  An Explanation of Heat Dome & Its Influence on Texas Weather this Week

Daily highs will certainly be on the warm side, but as many parts of the state have experienced a length of time without precipitation, we’ll be seeing humidity levels decrease which will make the heat a bit more tolerable for areas mainly along and west of the I-35 corridor.  While drier air will heat up more during the afternoon, it will cool down more quickly overnight and also decrease that summertime sticky feeling.  The eastern half of the state, which typically stays more humid and muggy, will still be dealing with heat index readings at uncomfortable levels between 105 and 108 degrees for at least the next several days.  Heat Advisories are in place through Wednesday evening for far northeast and east Texas and may be extended beyond Wednesday if necessary.

As mentioned above, rain chances this week be found primarily across our coastal regions.  Showers off the coast will develop each morning and tend to move onshore by early afternoon along the daily seabreeze. The expanding ridge of high pressure will keep most of the activity from moving much further north than the I-10 corridor, and much of the shower activity is expected to remain below severe limits.  Beyond Tuesday, we’ll see somewhat of a downtick in precipitation chances across coastal southeast Texas, with most of the chances remaining across central and south Texas coastal regions Wednesday through Friday. All in all, it looks like we’re in for a dry stretch this week for most of the state.  By this coming weekend, we may see chances for rain improve across the panhandle and far west Texas, but that’s too far out for certainty at this time.
