The following is a message from the National Weather Service for the Katy area:
After several days of unseasonably hot weather, Southeast Texas will undergo a dramatic shift. A strong cold front will cross Southeast Texas early Friday and usher in some of the coldest temperatures so far this autumn. Temperatures behind the front will fall into the 50’s early Friday morning and periods of rain and thick cloud cover will limit heating so afternoon high temperatures will likely only warm into the upper 50’s. Low temperatures by Saturday morning will fall into the lower and middle 40’s.
Unseasonably cold temperatures will persist on Sunday as another upper-level disturbance brings rain to the area. Again, the rainfall and associated cloud cover will limit any warm-up and temperatures will remain in the 50’s. The normal high temperature for this time of year is in the middle 70’s and the normal low temperatures are in the middle 50’s.
A second cold front will cross the region on Monday and bring another surge of colder temperatures to Southeast Texas. High temperatures will again remain in the middle 50’s north to around 60 south. The air mass behind the second front is dry and dry air cools faster at night so overnight low temperatures are
expected to fall into the lower and middle 30’s by the middle of next week.
