Heavy drenching thunderstorms today will spread across the Ohio Valley and the Northeast.
This weekend, a tropical wave will near Florida from the Caribbean. This wave will make for a breezy day along the eastern coastline of Florida, but more noticeable will be the thunderstorms. Thunderstorms that do form will bring more than your typical rainfall to parts of the Southeast as extra moisture will be injected into the storms.

July 30, 2006- The Weather Channel
South

Deep moisture in place, combined with daytime heating, and a weak disturbance in the atmosphere, will produce scattered showers and thunderstorms across parts of the southeast today. The best opportunities to see these showers and thunderstorms will exist across central and southern Mississippi, southern Alabama and Georgia, and the coastal Carolinas and Florida. Here the sea breeze will interact with boundaries left from storms yesterday to produce brief periods of heavy downpours and gusty winds with a few of the thunderstorms.

The Upper Mississippi Valley also stands out in regards to strong winds.

July 28, 2006- Accuweather
On Thursday, numerous thunderstorms ignited in the juicy air mass blanketing the eastern half of the nation. A frontal boundary across the southern Great Lakes enhanced the development of numerous storms with gusty winds, hail and drenching downpours. Strong thunderstorms knocked out power in the Chicagoland area and caused delays at O'Hare and Midway airports.


July 30, 2006- Accuweather





Before the heat spreads over the entire Great Lakes on Monday, the region will have to endure an active weather day, as a frontal boundary has triggered and will continue to trigger severe thunderstorms. As the hot air to the south interacts with the somewhat cooler air to the north, thunderstorms with damaging winds, hail and torrential downpours will erupt.

August 2006 Hurricane and Severe Weather Outlook

Click here for July 2006 Hurricane and Severe Weather Outlook.

These forecasts were developed during the first two weeks of December 2005.

I’ve included the dates of the Moon’s maximum declination north and south of the equator as well as its equatorial crossing. I’ve noticed that many hurricanes have formed or made landfall around these dates.

Aug. 1-2:
Significant storms focus on the Northeast and New England.

Aug. 6:
Moon attains maximum south declination.

Aug. 6-7:
The coastal areas from Virginia and North Carolina through New England are in for some severe weather in the form of storms producing wind and rain.

Aug. 9-12:
A tropical system may get its act together over Cuba and the Bahamas. Tropical moisture from this system or elsewhere should be pulled up over the Florida Peninsula and the Carolinas. Severe storms will develop over the Ohio Valley as well.
Another hot spot for hurricane development is shown off the eastern coast of Mexico in the western Gulf around 96 West Longitude and 22 North Latitude.

Aug. 12:
Moon crosses equator.

Aug. 11-13:
Gusty winds will prevail along the West Coast with storm potential further inland.

Aug 14-15:
Meteorological mayhem breaks out over the Southeast U.S. through the Ohio Valley as atmospheric elements combine over the area. One scenario shows a tropical system approaching the west coast of Florida and pushing inland with soaking rains. Another model suggests strong storms with damaging winds and flooding.

Aug. 16-18:
A strong storm system is indicated over New England and the Canadian Maritimes as energy moving from the west interacts with a warm, moist air mass.

Aug. 19:
Moon attains maximum north declination.

Aug. 19-22:
Several atmospheric ingredients will come together over the Southeastern States from the Big Bend of Florida into Georgia creating a threat of severe weather. The threat will extend into the Ohio Valley as well. It is possible that this signifies a tropical system or at least abundant tropical moisture that drops heavy rain over the Southeast.

Aug. 20-22:
Another potential Hurricane Hot Spot that also bears watching now extends from the central Gulf of Mexico into the Yucatan Peninsula.

Aug 22-23:
Increasing moisture over the central California coast may lead to anomalous rainfall.
A strong low pressure system develops over the western Great Lakes unleashing strong thunderstorms and gusty winds. (Forecast in italics was added on August 8, 2006)

Aug. 26:
Moon crosses equator.

Aug. 26-27:
The central Gulf of Mexico is still a concern for tropical activity during this period.
The West Coast States and Intermountain area will more than likely experience an influx of moisture setting off storms and flash flooding at this time.
An important area worth watching now is the U.S. Southeast particularly northern Florida through the coastal areas of Georgia and South Carolina. Severe weather, perhaps a tropical system, is possible here.

Aug. 28-30:
Tropical storm formation is possible over the central Baja Peninsula. An outbreak of severe thunderstorms is imminent over the Colorado Front Range and adjacent areas.
Tropical troubles are still brewing over a broad area from western Cuba through western Florida and into Georgia and South Carolina. (See August 26-27)

Aug. 30-Sept. 1:
The West Coast and Intermountain West should feel the effects of a strong monsoonal flow that will unleash heavy rainfall over the area. Abnormal amounts of moisture are shown over the southern California coast.
Another potential Hurricane or severe weather trouble spot forms over Louisiana.
The indications for the Northeast are that windy and stormy conditions will affect the Eastern Seaboard from around Washington DC northward into New England.

For some, there will be good news, as a cold front slicing through the Midwest will break up the heat and humidity - at least temporarily. This front, however, will pack a cruel twist, in that it will bring the potential for severe storms with it from the western and central Great Lakes back into Iowa. Damaging wind gusts will be the main threat to be on alert for; however, some storms will also have the capability of producing hail.

July 19, 2006- The Weather Channel
Midwest

Violent thunderstorms erupted in southern Minnesota Wednesday morning then raced off to the southeast toward northwestern Illinois. Once reaching Illinois the thunderstorms took a right turn and went south through western parts of the state. During the evening the storms turned again, this time to the southwest and took aim on St. Louis. Another round of severe thunderstorms is expected overnight tonight. At highest risk are southeastern Minnesota, northern Iowa, southern Wisconsin and far northern Illinois. Besides the threat of twisters, powerful winds, large hail and locally excessive downpours#up to five inches#are likely.

July 17-19, 2006 Forecast:

This potent weather system then continues toward the east over the Mid-Atlantic region and New England.

Results

July 17, 2006- Accuweather
The oppressive heat in parts of the Northeast will be eased a bit, but at a cost. A cold front coming down from Canada Tuesday will collide with the hot, humid air mass over the region. As this happens, the atmosphere will become unstable, and towering thunderstorm clouds will begin to build. A line of storms will march toward the East Coast during the day, but will likely not reach the big cities until later in the day or at night. The main threat with these storms will be from damaging winds and frequent lightning, but large hail and heavy downpours are also expected.

Here is some commentary on the July 2-4, 2006 forecast. This forecast was prepared between Nov. 16-28, 2005.

July 2-4Forecast: The tropics may begin to rumble as planetary indicators off the coast of Veracruz, Mexico suggest the possibility of tropical storm formation there.The Arklatex region shows signs of severe weather as moisture from the Gulf of Mexico is pumped into the area.

Results
The July 1, 2006 Accuweather Map above shows the development of thunderstorms and showers off the coast of Veracruz, Mexico. The Mexican Weather Bureau reported the following today:

Amplia zona de inestabilidad convectiva frente a las costas de Veracruz y Tamaulipas se asocia con nublados de convección moderada a fuerte, favoreciendo nublados con chubascos, tormentas y vientos fuertes. El sistema avanza hacia el Noroeste y se encuentra en vigilancia debido a su lenta evolución. (A wide area of convective instability off the coasts of Veracruz and Tamaulipas is asscociated with moderate to strong convection favoring showers, storms, and strong winds. The system is moving toward the Northeast and is being watched for further development.) (Rough translation is mine)

Forecast continues...
The Arklatex region shows signs of severe weather as moisture from the Gulf of Mexico is pumped into the area.


The map to the left (courtesy of Accuweather) shows the tropical moisture being pulled up over Texas and Louisiana.

Here Comes The Rain AgainSunday, July 02, 2006 2:18 PM EDT More News The Texas Gulf Coast, which had torrential rain for a couple of days nearly 2 weeks ago, is in for another bout of heavy, flooding rain over the next couple of days. A tropical low pressure system, which was in the southern Gulf of Mexico a couple of days ago, has been drawn northward. Tropical moisture has been concentrating around this system and, as it continues to be pushed northward, this tropical moisture will be shoved ashore into coastal Texas, resulting in heavy, drenching thunderstorms. The overall movement of this system will be slow, so parts of coastal Texas appear to be in for another thorough soaking. This story by AccuWeather.com Meteorologist Gerald Mohler.

Louisiana and Arkansas are in for some wet weather due to this system and other factors.
