Warm Fronts in the Pensacola Region
Warm frontal systems will usually pass through the
local area when the low moves into the east Arkansas/west
Mississippi area. Weather associated with the frontal
passage usually is multi-layered cloudiness with widely
scattered light rain. Warm-sector cloudiness and
visibility will depend on the wind velocity in the warm
sector. Warm fronts influencing the local area originate
from two synoptic situations:
1) In the first situation, a wave develops on a quasi-
stationary frontal system in the southwestern Gulf and
moves northeast. The wave center moves inland, usually
around Lafayette, Louisiana with the warm front trailing
southeast into the central Gulf. As the low center tracks
to the northeast, the warm front moves in relation to the
low. Typical warm frontal weather is experienced as the
front moves through the local area. Cloudiness and visibility
in the warm sector will depend on wind velocity in the warm
sector after the warm front moves north of the station.
Embedded thunderstorm activity is a frequent occurrence with
the passage of the warm front.
2) In the second situation, a cold front moves through the
local area and into the central Gulf trailing westward to
southern Texas. The local area experiences clear weather for
48-72 hours as the high pushing the cold front moves to the
East Coast. With continued eastward progression of the high,
the front in south Texas begins to move northeast as a warm
front and usually becomes connected with a new low developing
on the cold front moving into central Texas. As this low moves
east, the frontal system moves in relation to the low.
