Summary: In today’s post we dive into the eclipse forecast for next Monday, which for Texas is frankly not very good. As for our weather in Houston, we’ll see a warm day ahead of a front on Tuesday. That should bring us lovely, spring-like weather for the rest of this week.
Total solar eclipse
Although we are still a week away from the total solar eclipse on April 8, which will take place at approximately 1:30 to 1:40 pm CT for much of the line of totality across Texas, the forecast is pretty grim. Locally, in Houston, about 94 percent of the Sun will be covered on Monday at the peak of the eclipse. My preliminary forecast for next Monday is scattered to widespread rain showers with mostly cloudy skies. For areas along the line of totality in Texas, the outlook is not much better. The operational runs of both the GFS and European models have, consistently, shown nearly 100 percent cloud cover across much of the state during the early afternoon hours on Monday. There is a fair amount of support for this in the ensembles as an upper-level system crosses the southern plains. Many of these areas could see rain on Monday.
The map below shows the ensemble forecast for percent of the sky covered in clouds on Monday at 1 pm CT. For nearly all of the totality path in Texas, the value is about 75 percent. However, given the consistency in the operational models, I would lean toward a value higher than that at this time.
About this I would say a couple of things. First of all, we’re still a week out. Forecasts can and do change. But this is not a good place to be seven days from the total eclipse. If you really want to see the eclipse with clear skies, the northeastern United States looks like your best bet. Secondly, if you’re staying in Texas, the eclipse will still be quite a treat even with poor weather. Along the line of totality the sky will still get completely dark in the middle of the day, which will be an eerie experience indeed.
We’ll continue to track the eclipse forecast in the days ahead.
Monday
Today will be warm, but not quite as warm as we’ve been anticipating. Mostly cloudy skies should help to limit highs to the mid-80s for much of Houston. It will be a breezy day, with southerly winds at about 15 mph, and gusts up to 25 or even 30 mph. Low temperatures tonight will only drop to about 70 degrees. There will be about a 20 percent chance of showers tonight, and an even lesser likelihood of isolated thunderstorms ahead of an approaching front.
Tuesday
The front should push into Houston during the morning hours on Tuesday, reaching the coast by around noon. We’ll see an additional, low chance of rain with the front’s passage, but then we’ll see quickly clearing skies and drier air moving in with northwesterly winds. These clearer skies will allow highs to briefly reach the lower 80s, but lows will drop into the 50s on Tuesday night.
Wednesday and Thursday
These will be a pair of gorgeous spring-like days. We’re talking highs in the low- to mid-70s, plenty of dry air, and lots of sunshine. Lows on both nights should drop into the low 50s in Houston, with cooler conditions for outlying areas. Seriously, these look like A+ days.
Friday
This will be another nice day, with highs of about 80 degrees. A few scattered clouds will be possible with the return of the onshore flow, and lows on Friday night will drop to around 60 degrees.
Saturday and Sunday
Both of these days should see highs of around 80 degrees, with partly sunny skies. Sunday will see a decent amount of humidity, and we cannot entirely rule out some light rain showers later in the day. But for the most part, the weekend looks excellent for outdoor activities.
Next week
As mentioned above, rain chances start to increase on Monday, and through the early part of next week, in response to an upper-level system. It’s still too early to have too much confidence, but we’re talking days in the low 80s before a weak front (probably) arrives in the middle of the week.
