Windy days should blow us into a nice weekend

First, the good news.

The forecast for Easter weekend looks perfect. Temperatures in the 70s and 80s, light winds, sunny, dry.

Thursday's forecast calls for highs in the 80s, with afternoon sunshine and winds. The winds will keep blowing into the evening, and there's a 30 percent chance of rain after midnight. Lows will be in the 60s.

Now, the bad news: We could all blow -- or float -- away before the weekend arrives.

Winds will pick up to 20 to 25 mph Thursday and Friday afternoons, and Friday afternoon could see severe thunderstorms, according to the latest National Weather Service forecast.

Rain will become more likely around daybreak Friday, and as the day warms up into the 70s, the chance of severe weather rises in North Texas, although the risk remained slight in the most recent forecast.

But the forecast also called for 70 percent chance of showers, thanks to a powerful upper-level low pressure system, also called a trough, that was moving toward Texas from the California coast.

A "dry line" of desert air will be pushed into North Texas by the trough as it continues east, the weather service said.

This dry air will collide with moist air from the Gulf of Mexico that has been rolling into the region the past few days, courtesy of the stiff southerly winds.

Storms will develop Friday afternoon where the two air masses collide, the weather service said.

There possibly will be enough severe weather to form a squall line of severe thunderstorms from north to south, the weather service said.

"It's really going to fire up those storms," said Amber Elliott, meteorologist with the weather service office in Fort Worth.

But the severity of the storms, Elliott added, "depends on all the ingredients."

"Now that everything is coming together, we're just working out the timing," Elliott said.

Isolated thunderstorms may pop up late Friday morning or early afternoon, but not because of the dry line.

Elliott explained that the abundant moisture might get riled from instability aloft caused by daytime heating.

Be ready after lunch for storms associated with the dry line, Elliott said.

The rain and winds may continue into Friday evening, and the overnight lows will be in the mid-40s.
