Meteorology

July 5, was an active day for severe weather with well over 400 wind damage reports extending from the Southeast all the way back into the Mid-Atlantic Region.

This upper air map is from July 5, 2012 and it’s from the 500mb level which is roughly about 18,000ft above the ground.

Another air mass that we have is known as "marine time polar air".

Marine time tropical air mass is made up of moist and warm conditions.

Continental arctic air mass is known for its very frigid and dry air.

Say it’s not so, but we could be very well on the verge of entering into an EL-Nino cycle soon. How soon?

El-Nino is marked with having warmer waters in the Pacific Ocean, so how can it have impacts on Annapolis Maryland?

Another type of air mass that we are going to talk about is called Continental Tropical also known as CT.

As a meteorologist you are taught quickly the term Air Mass.

The morning weather map for July 5, shows us the current surface pressure readings.

The brief reprieve we saw this week in terms of temperatures has run its course as warmer temperatures will be reinforcing itself into the picture for the latter part of this week and weekend.

This past weekend we saw a massive line of storms impact large areas of the country from Iowa to Maryland in what is known as a Derecho.

January 2012: Started out dry as the area only received 1.06in of rainfall which is about .76in below normal leading to an annual deficit of .76in.

So why is there so much heat and humidity rising up into the Northern Plains creating a surge of hot weather?

The heat wave of June 20, 2012 not only marked the beginning of summer but also the beginning of a strong push of warm air that will be in the Northeast for the next couple of days. On the map we see that high pressure was located along the Eastern Sea...

Typhoon Guchol, these past few days, had made it to Super Typhoon strength which would be the same as saying that it was a CAT 3 or larger storm.

El-Nino is marked with having warmer waters in the Pacific Ocean, so how can it have impacts on Austin Texas.

Looking at our weather map above we can see a cold front moving through the states of Oklahoma and Kansas.

On June 17, 2012 a line of strong storms began to develop around 5pm CDT.

If you look at our weather map above you see a warm front extending from Iowa into the Great Lakes region.
