Forecast Discussion:

We can all finally stop talking about the low now located over the eastern seaboard; it’s pretty much a non factor in our forecast at this point. However, we are tracking another low pressure system that’s ready to swing into the region later today. This low will carry a hefty amount of instability along with it, which could cause some of the storms we’re expecting later today to become severe in nature. The good amount of sunshine and surface heating we’ll receive this morning will play a major role in the development of these storms later today. We’ll first catch some popup showers and thunderstorms throughout the late morning and early afternoon hours, a few of which may produce some small hail, but the stronger storms will not develop until later. We’ll have a brief lull in the action as temperatures warm up to around 80° here in Lafayette. An organized band of thunderstorms will setup to our southwest during the late afternoon and move northeastward eventually arriving just after 7:00 pm .This line of thunderstorms will feed off of the instability at the surface while the upper level jet extends cloud tops within the line higher into the atmosphere. Some of the larger cells embedded in this line may produce large hail and wind gusts in excess of 60 mph. The threat for severe weather will linger until midnight at the latest, after that we’ll be left with some scattered rain with a few claps of thunder mixed in. The cold front will then pass tomorrow morning wit ha few additional rain showers as temperatures only warm up into the mid to upper 60s. A secondary and weaker cold front will arrive on Saturday possibly accompanied by a couple isolated rain showers though the most of us will remain dry. Afternoon highs that day should be near 65°. It’s Sunday that that the cool and dry air mass following the cold front will really settle in; afternoon temperatures throughout the viewing are will only top out in the mid to upper 50s with overnight lows expected in the mid 30s.
