FIRST WARNING: Fantastic weekend – stormy, colder, and potential threat for wintry weather next week

Forecast

AUSTIN (KXAN) — Calm winds, clear skies and low dew points overnight made for a cold start to Saturday with another freeze for most areas outside of the Austin City Limits. The cold temperatures won’t last long, as we have sunny skies and highs near 70 degrees in your forecast this afternoon.

The pleasant weather continues into your Sunday with another afternoon near 70 degrees, but increasing clouds as we head towards the evening hours.

If you like this sunny weather, ENJOY IT WHILE IT LASTS THIS WEEKEND! Two storm systems will make for a wet, cold, and stormy week beginning as soon as Sunday night.

Storm #1

The first storm to impact Central Texas will arrive late Sunday/early Monday. This system is a low pressure that will move out of Northern Mexico and bring widespread chances for rain and thunderstorms for much of the day Monday.

Temperatures are expected to be a few degrees cooler than Sunday, but mostly because of the rain and cloud cover – with highs in the 60s. No cold front is accompanying this system, nor any threat for wintry weather. Although, prepare for a potentially hectic Monday morning commute with rain chances peaking during the morning rush hour.

Rainfall totals look healthy, with widespread 0.5″ to 1″ totals, and the possibility for isolated totals near 2″+.

GRAF forecast rainfall through Monday evening

Conditions will improve from west to east by Monday evening with warmer and drier weather for Tuesday.

KEY TAKEAWAYS: Strom #1 will be an all rain event with isolated thunderstorms and heavy rain. Impacts will be confined to Monday only. Temperatures will be well above freezing, but cool.

Storm #2

Before getting into the details, be advised that this forecast is highly subject to change. However, any time there is the potential for hazardous (and especially, wintry) weather, it is our job to give the best forecast with the information and data available at that time. This will also NOT be a repeat of February 2021.

Unlike storm #1, storm #2 will arrive with a cold front. Meaning, along with chances for precipitation, temperatures are trending colder as more model data comes in.

After another warm afternoon Wednesday, the front looks to arrive around midnight and into the early morning hours of Thursday. Strong north winds will accompany the front, as well as a sharp drop in temperatures.

The potential for rain begins Wednesday night, with the possibility of a switchover to wintry mix Thursday as temperatures continue to drop to near or below freezing.

At this time, both of our long-range models are picking up on the possibility of wintry mix in Central Texas. However, one model has the precip sticking around longer (GFS), while the other has the precip ending a lot sooner (EURO).

KEY TAKEAWAYS: Precipitation type and amounts are still to be determined for storm #2. But timing is coming more into focus with impacts beginning Wednesday night and lasting through the day Thursday. Temperatures are also

As mentioned above, lots can, and will, change with this forecast. But be mindful that next week is looking wetter and colder – and the potential is there for some wintry mix showers late in the week.
