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.
