Good morning. A cold front is sagging southward toward our region, and this will set the stage for several cooler and rainy days. It certainly will not rain continuously from now through Saturday morning, but there will be periods of moderate and potentially heavy rainfall. Some areas will see accumulations of rainfall, over time, that may produce some street flooding. For this reason we have initiated a Stage 1 flood alert from noon today through Friday night.

Wednesday
Conditions are warm and humid this morning, with lows having dropped only into the mid-70s. The front will reach areas northwest of Houston by around noon, push into the city this afternoon, and reach the coast late this afternoon or early evening. I expect to see a broken line of showers and thunderstorms with the front, but the bigger concern will likely come tonight and later this week. Why? Because the front is going to get hung up right along the coast, and as a result should help to generate nearly stationary showers and thunderstorms over time. Temperatures today should reach the low 80s ahead of the front, and drop into the low 60s tonight.
Thursday and Friday
The period from Thursday morning through Friday night is when we’re most concerned about the potential for heavy rainfall. I wish I could be more precise in terms of impacts, but the short-term modeling is not terribly consistent with where the heaviest rainfall will set up. As a result, we’re going to have to continue to predict widespread accumulations of 2 to 6 inches, with higher isolated totals.

I noted above that our primary concern is stationary storms, which this kind of setup—springtime, stalled front, plenty of moisture, and atmospheric disturbances—favors. For most of us, the rain totals should be completely manageable. Soils are reasonably dry, and the rains will be spread out over two days. But some locations will very likely see street flooding, so be weather aware the next couple of days. Highs on both days will be in the upper 60s to about 70 degrees, with lows in the upper 50s to 60 degrees.
Saturday
Fortunately, we’re increasingly confident that this mess is going to move out by Saturday morning, and this should lead to a mostly cloudy day, with highs of around 70 degrees. Rain chances will be quite low after the morning, perhaps only 10 percent. Overnight lows will drop to around 60 degrees.

Sunday
The same goes for Easter Sunday, in the sense that we expect the day to be rain-free. We also should see some partially clearing skies. So look for highs in the mid- to upper-80s, therefore, with a splash of sunshine. With dewpoints around 60 degrees, the air will also feel decently dry. So all in all, it should be a rather nice holiday.
Next week
We have no weather concerns for next week. The region should see a slow warming trend such that temperatures reach the mid-80s toward the end of the week, with humidity levels creeping back up.
