A weak elongated cold front associated with a 990MB low, is currently moving south, towards the Gulf of Mexico. Subsequently, frontolysis will occur in the Gulf of Mexico about 24-36 hours from now. The degenerated cold front will kink all the way to the BOC, and will leave the Gulf of Mexico in a relatively baroclinic state. The surface pressure will then decrease, and showers and little thunderstorm activity will then form due to the dynamic forcing from the stationary front. A 1030MB anticyclone is expected to build over eastern Texas about 30 hours from now. The anticyclone will act as a catalyst for cyclogenesis over the GOM, since it will help advect cold air southward to help displace the warm air to the south (look at the illustration below). The developing system will quickly stride towards Florida, and will increase the chance of precipitation by nearly 50% Tuesday. After that, HERE COMES DRAMA lol!
After this systems passes over Florida, A 1035MB high is expected to build over the eastern U.S. about 72 hours from now, and will blow cold air through much of the south. Nevertheless it is not over yet, an enormous 1050MB high will build across the Midwest, and advect bone-chilling air to the south, and temperatures will be in the 30s for much of Florida.

Hurricane Dolly made landfall at southern Texas early this afternoon as a category 2 hurricane, with maximum sustained winds at 100 MPH with higher gusts. The primary threat right now are the high winds, some damage to structures are expected. Subsequently as the Dolly weakens tonight, rain will be the primary threat, accumulating up to 16 inches at some areas. Elsewhere in the united states, a stationary front associated with two areas of low pressure to the west and east will enhance the chance of precipitation along the southern states. A high pressure is dominant over the northern midwest, thus, the chance of rain is low. The western states will get a break from the heat as several mid latitude cyclones are increasing the potential of rain over the area.
