Houston Weather: Tropical Disturbance Expected to Bring Rain Friday

Tropical Disturbance Update

• 💡 A tropical disturbance off the Florida panhandle is unlikely to develop into a depression or storm due to limited time and open water.
• ⚠️ Despite its disorganized state, the system is expected to be a heavy rain maker for the central Gulf Coast, impacting Houston by Friday.

Houston Weather Forecast

• ☀️ Houston will experience hot and humid conditions through Thursday, with a dusty sky from Sahara Desert dust.
• 🌧️ Rain chances increase significantly on Friday, starting in the morning with potential for locally heavy downpours and street flooding.
• 💨 The system is moving west at 12 mph, with pressures not significantly falling, indicating a lack of strong development.

System Dynamics and Shear

• 🌊 The disturbance is interacting with land and experiencing wind shear at mid-levels, which is disrupting its organization.
• 🌪️ Wind shear prevents vertical stacking of the storm's circulation, tearing thunderstorms away from the center and pushing rain ahead of the trough axis.
• 🛰️ Satellite imagery shows an open wave, not a closed area of low pressure, further indicating a lack of significant development.

Model Projections and Rain Impact

• 📊 Tropical spaghetti models show agreement on the system moving west and then north through central Louisiana.
• ⛈️ While the center may not directly impact southeast Texas, wind shear is expected to blow convection into Houston and southeast Texas on Friday.
• 💧 The forecast indicates off-and-on rain and thunderstorms throughout Friday, with potential for heavy rain pockets.

Broader Texas Weather Impact

• 🚫 Unlike some past weak tropical systems, this one is not forecast to bring significant rain to central or west Texas, which is considered a silver lining.
• 🏞️ Most of Texas is expected to remain dry, with rain primarily affecting southeast Texas and moving north into Arkansas.
• 🗓️ Lingering moisture may bring some rain to East Texas and Houston on Saturday, but the Hill Country is expected to stay dry.

Hurricane Preparedness

• 🏠 Residents, especially on the coast, are advised to monitor forecasts, check evacuation plans, and prepare for potential shelter needs.
• ⚡ Inland areas should prepare for potential power outages if a major storm were to occur.
