Houston Weather: Cold, Wet Start to December

A Dramatic Shift in Houston's Weather Patterns

After an unusually warm and dry fall in Southeast Texas, Houston's weather has taken a dramatic turn. The recent arrival of a potent cold front has ushered in a winter-like pattern, bringing widespread rain, chilly temperatures, and even isolated flooding risks. This abrupt change marks a significant shift from the extended dry spell the region experienced just weeks ago.

Recent Storm System and Flooding Concerns

The transition began with a stormy weekend that saw a cold front sweep through the area. While the storms weren't classified as severe, they brought intense rainfall rates, with some parts of Houston recording over 2 inches of rain per hour. The I-45 corridor saw nearly 4 inches of precipitation within a 24-hour period, significantly saturating already thirsty ground. This downpour, while welcome after months of drought, created immediate concerns about flash flooding, particularly in low-lying areas and neighborhoods with poor drainage.

Monday's Forecast: A Day of Dreary, Chilly Rain

As we head into the first week of December, Houstonians should brace for a cold, wet Monday. Widespread rain is expected to dominate the day, creating dreary conditions and potentially challenging commute conditions. Forecasters advise allowing extra travel time during the morning rush hour as wet roads and reduced visibility could impact traffic. Temperatures will remain unseasonably cool for early December, with highs struggling to reach the mid-50s and a persistent chilly drizzle likely throughout the day.

Extended Forecast: Chilling Mornings Ahead

The cold air mass accompanying the front will linger into the middle of the week, bringing even colder temperatures. Tuesday and mornings are expected to see lows in the upper 30s and low 40s across the region. This means frosty conditions and the need for heavier outerwear during early commutes. While daytime hours may offer some reprieve with slightly warmer temperatures, the overall pattern will remain brisk and damp, a stark contrast to the mild fall weather Houstonians have grown accustomed to.

Flooding Risks and Safety Precautions

With the ground already saturated from the weekend's deluge, the risk of flash flooding remains elevated, particularly in coastal counties. Monday carries a level 1 out of 4 risk for flash flooding in these areas. Residents are urged to:

• Avoid driving through flooded roadways – "Turn Around, Don't Drown"
• Stay updated with local weather alerts via trusted sources
• Clear storm drains and gutters around property to aid drainage
• Keep emergency supplies in vehicles for unexpected weather events

Embracing the Seasonal Change

While the abrupt change to colder, wetter weather may require some adjustment, it's a natural shift that brings much-needed relief to the region's drought conditions. As Houston transitions into December, residents should prepare for a more traditional winter pattern, with cooler temperatures and periodic precipitation. The recent weather pattern serves as a reminder of the Gulf Coast region's dynamic climate and the importance of staying weather-aware throughout the year.
