We have some big changes moving in later this week as Arctic air moves south, sending a cold front through south Texas Thursday. Showers are likely with the front Thursday as temperatures fall. It will be chilly Friday and Saturday but the coldest air won't arrive until Sunday and Monday with daytime highs only in the 40s and nights dropping into the 30s. A freeze is possible Saturday night through Monday night inland and possibly closer to the coast. There will also be some rain this weekend, mainly Sunday and Monday with the potential of a wintry mix at times. We'll have updates and more details through the week as new data comes in.
Monday night will be foggy with dense fog in areas by morning and lows in the lower 60s with light southeast winds.
The fog will lift by mid-morning Tuesday and we'll gradually see some sunshine in the afternoon with a warm day. Highs will reach the low to mid 80s inland and upper 70s at the coast with southeast winds at 8-15 mph.
Wednesday will also be warm with partly sunny skies and highs in the lower to mid 80s and the chance of an isolated shower.
Showers are likely Thursday with high temperatures staying in the low 70s then falling as northerly winds increase to 15-20 mph late in the day, causing temperatures to drop into the low 40s Thursday night.
Friday looks dry but still mostly cloudy and chilly with high temperatures only in the 50s.
