Good morning. Conditions are almost summer-like this morning, with lows coming down only into the low-70s for much of the region, with dewpoints not far behind. Southerly winds, too, are pumping moisture inland to set up the potential for storms late tonight and Thursday morning, and we’ve got full details below. Easter weekend also continues too look good, weather-wise.
Wednesday
Today will be a mostly cloudy affair, with highs perhaps getting up to around 80 degrees for most of the region with lots of humidity. Houston should see some scattered showers later this afternoon, but they’re likely to be of the light-to-moderate variety as the atmosphere won’t be ready to break open just yet. South and southeast winds will blow all day, gusting at times to around 20 mph.

Wednesday night and Thursday
A line of severe weather will develop before midnight to the west of the Interstate 35 corridor, and progress eastward across the state on Thursday morning. For areas west of Houston (and Katy) and north of Houston (and The Woodlands) chances are that some of these storms will hold together to present a threat of heavy rainfall, and perhaps some hail. But a fairly strong capping inversion should hold over the metro region itself, and the effect should be a breaking of the line of thunderstorms as it near the Houston region around sunrise. Here’s how the NAM forecast model depicts the “line” of storms at 8am Thursday.

The bottom line is that conditions will be fine today and likely this evening for the Houston region, with just some scattered showers. The bigger concern will come around sunrise on Thursday, in the midst of rush hour, with the potential for strong thunderstorms. For now we think Houston will see some downpours at that time, but nothing too severe that lasts too long. Accumulations close to 0.5 inch are likely near the coast, with perhaps 1.5 inches of rain for inland areas like The Woodlands. We’ll have a comprehensive post up by 6:30am CT Thursday with the latest.
