The warm sector is a near-surface air mass in between the warm front and the cold front, on the equatorward side of an extratropical cyclone. With its warm and humid characteristics, this air is susceptive to convective instability and can sustain thunderstorms , especially if lifted by the advancing cold front.
The warm sector is a near-surface air mass in between the warm front and the cold front, usually found on the equatorward side of an extratropical cyclone. With its warm and humid characteristics, this air is susceptive to convective instability and can sustain thunderstorms , especially if lifted by the advancing cold front.
The warm air overrides the cooler air and moves upward. Warm fronts are followed by extended periods of light rain and drizzle due to the fact that, after the warm air rises above the cooler air (which remains on the ground), it gradually cools due to the air's expansion while being lifted, which forms clouds and leads to precipitation.
A stationary front is often present near the area of freezing rain and serves as the focus for forcing moist air to rise. Provided there is necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely nimbostratus and cumulonimbus if significant precipitation is involved.
Frontogenesis is a meteorological process of tightening of horizontal temperature gradients to produce fronts. In the end, two types of fronts form: cold fronts and warm fronts. A cold front is a narrow line where temperature decreases rapidly. A warm front is a narrow line of warmer temperatures and essentially where much of the precipitation ...
The red line shows how freezing rain forms, from snow through the warm layer and then into the "supercooled stage". Freezing rain is often associated with the approach of a warm front, when subfreezing air (temperatures at or below freezing) is trapped in the lowest levels of the atmosphere while warm air is advected aloft.

There might be a possibility of rain after a long drought. The Fort Worth National Weather Service predicts:. Friday, Oct. 25: Day: Sunny, with a high of 89. South southwest wind 5 to 10 mph.
Diagram of a cyclone in the early stages of occlusion in the Northern Hemisphere. In meteorology, an occluded front is a type of weather front formed during cyclogenesis.The classical and usual view of an occluded front is that it starts when a cold front overtakes a warm front near a cyclone, such that the warm air is separated (occluded) from the cyclone center at the surface.
