Week Rumblings (Sept 18, 2013)

Cardboard skies have given way to a beautiful Wednesday heading into what looks like a dreary end of the week. This doesn’t necessarily include the weekend.

Thursday will be hot and humid with thunderstorms likely on Friday as we will reside in the ‘warm sector’ of a mid-latitude cyclone. The warm sector is a region of warm moist air that is located between the associated warm front and cold front of a low pressure system. Typically, the warm sector is a nice place to look for thunderstorm development as the cold front sweeps behind acting as a lifting mechanism. This will be the case on Thursday with hot and humid conditions in place, and an increased chance of thunder on Friday when the cold front moves through.

Forcasted surface map for Thursday evening showing Michigan in the warm sector behind the red warm-front, and blue cold-front.

Cooler and drier air will move in for the weekend as the cold front wipes this mess clean. An area of high pressure will dominate this weekend bringing temperatures in the mid 60s and clear skies to the area.

Tropical weather is off to a slow start as Tropical Storm Humberto wanders along disorganized out in the Atlantic. Humberto is expected to remain a Tropical Storm, and take a journey northward. A broad region of low pressure over the Yucatán Peninsula looks promising, but remains plagued by its own disorganization. As this area moves north and west, it is expected to achieve depression status, but this is over the next 48 hours.

In the Eastern Pacific, Tropical Storm Manuel is docking along the Baja peninsula. Manuel is actually on the weather map above painted as a Tropical Depression in the coming days.

      Had lots of weather tension built up after a week of studying for Dynamics today! Felt pretty good about it. Can’t make Current Weather tonight, but will try to be there next week.
