SYNOPSIS AND OUTLOOK
Upper-level high pressure building into the area should keep it partly cloudy and warm today with only a very slight chance of a passing shower. Rain chances will slowly begin to creep up tomorrow as an upper-level low to the west moves northeast towards the Plains.
This morning a mostly stationary cold front extends east from the Florida Straits and the Bahamas to the adjacent Atlantic. To the northwest, a stationary frontal boundary extends from a low in southeast Colorado to a low near the Black Hills of South Dakota. To the north, a slow-moving cold front extends east from the low in South Dakota to the Great Lakes and a low in eastern Canada.
At the upper-levels, we are back in a more amplified pattern with a deep upper-level low and associated pressure trough over New England and the adjacent Atlantic, a high pressure ridge extending northeastward from East Texas to the Great Lakes region, while further west another upper-level low is along the central California coast with an an associated trough dipping over the western third of the U.S.
Partly cloudy skies and seasonably warm temperatures will gradually give way to mostly cloudy skies and a chance for rain as we move through the later part of this week. The upper-level low over California will move northeastward, along with a trough, into the Plains by Friday. Though the best chances for rain will remain to our north, some storms could drift south into Southeast Texas.
An area of disturbed weather northeast of the Bahamas is associated with an upper-level trough interacting with a weak frontal boundary at the surface. This area has a 10% chance of developing over the coming 24-hours and a 50% chance of developing over the next 5 days. Elsewhere, storm development is not expected in the Tropical Atlantic Basin at this time.
