Welcome to the month of May! May is typically the wettest and stormiest month of the year for Central Texas, and there are some early signs May 2023 might live up to that reputation.

Quiet weather will be in place for the first half of this week, but the weather pattern is predicted to turn more unsettled Thursday when a series of small low pressure troughs begin moving across Texas out of Mexico. Periods of rain showers and scattered thunderstorms are forecast to continue across the region between Thursday and Sunday. Heavy rain is not expected. Forecasts for next week show an other period of rain and thunderstorms developing sometime between Wednesday and Friday. This period of rain has the potential to cause somewhat higher totals of rain.

Warm temperatures are forecast over the next ten days, but no unusually warm weather is expected.

Here’s a breakdown of this week’s weather:

May Day is May 1

You might not realize it, but May Day – an ancient spring festival in the Northern Hemisphere – is an astronomy holiday. It’s one of the year’s four “cross-quarter” days. That is, it’s a day that falls more or less midway between an equinox and solstice. In this case, it’s between the March equinox and June solstice. We’re half way through spring and just 6 weeks until the start of astronomical summer!
