The Upper Low That Wouldn’t Go

September 15, 2009

Remember how I was talking all last week about my “reliable model” saying that this system would park itself overhead and not move? It was right. It appears that our upper level and surface features will sit still through at least Thursday, and could actually retrograde to our west as it weakens by the weekend. That means rain chances will go down, but it will be a slower process than mentioned yesterday. I guess it hasn’t been all bad. Yesterday we saw some healthy storms in the afternoon, but due to some slightly drier air creeping in, there was a great view of these growing storms through most of the afternoon. A true treat for any weather nerd. And now, the forecast.

Tuesday: Mostly cloudy with a 70% chance for thunderstorms. Most of us will only see 1-2 hours worth of rain in this set up, though isolated totals could eclipse three inches. Highs will be in the middle to upper 80s. Wind will be from the southeast at 8-16 mph.

Tuesday Night: Mostly cloudy with a 50% chance for thunderstorms. Lows will be in the lower 70s.

Wednesday: Mostly cloudy with a 60% chance for thunderstorms. Highs will be in the upper 80s.

Wednesday Night: Mostly cloudy with a 40% chance for thunderstorms. Lows will be in the lower 70s.

Thursday: Mostly cloudy with a 60% chance for thunderstorms. Highs will be in the upper 80s.

Friday through Sunday: Rain should become more scattered over the weekend, but the threat will remain in some capacity through Sunday. I’ll leave a 40% chance for mainly afternoon thunderstorms each day. Highs will be in the upper 80s to near 90, with lows in the upper 60s to near 70.
