Brooks's Blog II: Sunday afternoon storms now possible

The latest weather data, becoming available just this Saturday evening, raises the possibility for not just showers during the afternoon, but the chance for a thunderstorm.

This is my second blog entry of the day, but the first of the evening shift: UPDATE-- A warm front will push into Houston tomorrow, producing overcast skies, drizzle and showers. By afternoon, with temperatures rising through the mid-70s and a weak upper-level disturbance interacting with the boundary, a few isolated thundershowers are possible too. These will likely not be severe, but they could produce isolated pockets of heavy rain with occasional thunder. The big show comes in Monday night, as a cold front shoves tomorrow's warmer air mass out of the region for the better part of a week. The wedge-effect of the cooler air will force air to rise into tower cumulonimbus clouds with the potential to produce big downpours and frequent lightning. Some of the storms could, "train", where they form and re-form over the same, already-soaked, locations. Localized rainfall totals between tomorrow and Tuesday morning may surpass 3" in spots which could lead to street flooding at the height of it early next week. At least there's no immediate drought danger. Temperatures will cool dramatically, with highs only reaching the low 60s late next week. It'll only be brief, as some long-range models suggest we may top out in the mid and upper 80s before too long. Gotta love the ups and downs of the season. As of March 1st, it's, "meteorological spring" -- the months of MAR-APR-MAY -- when global patterns resemble spring more than winter. The astronomical spring ("vernal equinox") doesn't happen until March 20th. By the way, speaking of dates, March 11th marks the start of Daylight Saving Time when we lose and hour of sleep, but gain an hour of sunlight during the evening. -Brooks Garner
