The week begins with skies gradually filling with cloud cover, accompanied by a brief layer of shallow fog in some areas. That fog will fade quickly as the morning progresses, giving way to brighter conditions by mid-morning.

Temperatures start mild, in the lower to mid-60s, before climbing steadily into the mid-80s this afternoon. In portions of the southeast, where cloud development is more persistent, highs will be held back slightly, topping out in the lower 80s instead. Southerly winds will build through the day, reaching 10–15 mph with gusts up to 20 mph, adding a touch of breeze to the otherwise warm conditions.

Looking ahead, an upper-level disturbance is on track to arrive later this week, ushering in cooler temperatures and the potential for precipitation.

Dallas/Fort Worth: An approaching storm system will bring widespread showers and storms Wednesday morning through early Friday. Heavy rainfall and localized flooding are possible, with the greatest coverage of storms expected Thursday into Thursday night. A few storms may become strong to severe. Rainfall totals of 1–2 inches are expected, with isolated amounts exceeding 4 inches.

Waco & DFW: Unseasonably warm conditions continue early this week, with record highs likely to be tied or broken. Highs will remain in the 80s through midweek, with some locations in the Big Country breaking into the low 90s today.

Austin & San Antonio: Weather conditions mirror Sunday, with low clouds and fog in the east this morning followed by mostly sunny skies. Highs will again be well above normal, ranging from the mid-80s to low 90s. Rain chances return Wednesday night into Friday morning, bringing cooler, more seasonable temperatures.

The National Weather Service reports a dynamic start to the week across the country:

• West Coast & Sierra Nevada: Heavy snow blankets the Sierra Nevada Mountains today, while rain and embedded thunderstorms impact Central California. Rain and higher-elevation snow are expected in the Pacific Northwest Tuesday, tapering off by Wednesday.
• Rockies & Plains: Low pressure over the Central Rockies will bring snow to higher elevations and rain to lower valleys. Scattered showers and thunderstorms expand into the Northern and Central Plains, reaching the Mississippi Valley by Monday evening.
• Great Lakes & Northeast: Lake-effect snow continues downwind of Lakes Erie and Ontario, tapering off overnight. Snow will also develop across northeastern New York and the Northeastern Mountains through Tuesday.
• Florida: Onshore flow will produce scattered showers over southeast-central Florida through midweek.
