I hope everyone is planning a wonderful time outside for Memorial Day Weekend. It’s the beginning of the warmth up north, and probably the last time it won’t be too hot down south.

At 853PM, CT, Houston was reporting a temperature of 72 degrees. Moisture in the atmosphere was high, after rain this afternoon. There will likely be some fog and low clouds overnight. The bulk of the rainfall has shifted towards the Mississippi Delta, however a weak upper level trough remains over east Texas, which means that there won’t be any real clearing tomorrow.
With the trough hanging out in eastern Texas will continue to generate cyclonic flow in the western Gulf. Showers with some embedded thunderstorms will be more frequent and wider in coverage over Louisiana, on the east side of the circulation, but lingering moisture and scattered showers will remain a possibility throughout the remainder of the holiday weekend, with precipitation more likely Sunday than Monday.

There is close correlation between precipitation and temperature forecasts the next couple of days. There will be some wild differences in our verification scores! Precipitation has moved all the way over the Louisiana.

Most of Texas has seen rough weather this summer, including Houston and the Metroplex. Houston’s came early on in the season, when hundreds of thousands of local residents lost power, and 4 were killed when a squall line moved through the region on May 16th. Now, the heat is building in the south, and surely, that will be story moving forward. Right?

At 453PM, CT, Houston was reporting a temperature of 89 degrees with clear skies. Severe weather was forecast from border to border thanks to a broad lee trough sneaking into the Plains from the Rockies. This evening, there are showers and storms as far southeast as a line from Livingston to Hunstville, but these are fueled by moisture from the Gulf streaming into the area of low pressure.
The trough is going to inspire an array of individual short waved lows, including one in north Texas. Tomorrow, showers and storms will remain closely tied to the rotation in northern Texas, which will allow a dry day along the Gulf Coast. The vorticity maximum moving through the south central US won’t be enough to bring rain fall all the way to Houston on Tuesday, but the moisture will lead to morning for and haze before sunrise.
