SYNOPSIS AND OUTLOOK
Partly cloudy skies, seasonably hot temperatures and a chance of isolated to scattered showers and thunderstorms will persist through tomorrow as a weak mid and upper-level low drifts over West Texas and the upper-level high pressure ridge remains centered somewhat to the east.
This morning we are seeing a fairly typical summer-time weather picture, with a surface high near New Orleans and a surface low over northern Mexico. To the north, we continue to see two semi-stationary cold fronts splitting the country in half. In the west, the first cold front extends all the way from a low in southern Nevada to the Great Lakes with attached lows located also along the Arizona-New Mexico state-line and over the Oklahoma Panhandle. The second front extends south from the Great Lakes to a surface low in Georgia and then eastward into the Atlantic. High pressure has developed behind both fronts over the Northwestern and Northeastern parts of the country.
At the upper-levels, we are seeing a weak amplified pattern with a weak low pressure trough along the East Coast, a large high pressure extending north from the Deep South to the Great Lakes and Canada, a weak upper-level low over West Texas and a larger upper-level low and associated trough over the Dakotas.
Partly cloudy skies and seasonally hot temperatures will prevail through tomorrow with a slight chance of isolated thundershowers. We may see some increase in rain chances by mid-week as northerly winds develop aloft and the cold front to the northeast drifts southwestward into East Texas.
Tropical storm development is not expected in the Tropical Atlantic Basin at this time.
