Strong-To-Severe Storms Head Into North Texas
FORT WORTH (CBSDFW.COM) - While all of North Texas is under a Slight Risk for severe storms through the entire day, the main event will be a line of storms that moves across North Texas during the Tuesday afternoon and early evening hours. The storms that develop will be along a cold front to our west. Some of the storms or storm segments will become strong-to-severe, with the potential to produce damaging winds, large hail, frequent lightning and locally heavy rainfall.
During the morning commute, look for isolated showers and thundershowers (a 20 percent chance) for the Metroplex, coming from a small upper level disturbance -- meteorologists call it a short wave -- pivoting through over the dry line and cold front. The main storm line stays north and west of the Metroplex.
During the midday hours, scattered showers and storms are possible across the Metroplex (a 30-40 percent chance) and much of North Texas with the exiting short wave. As the day progresses, the large upper level low begins to push northeast from New Mexico. This will push the cold front and a surface low across North Texas during the afternoon hours. Storms will develop and strengthen along the cold front, but will be positioned west.
The main event will happen between 3:00 p.m. and 7:00 p.m. on Tuesday. The storm line will enhance and should develop into a well-pronounced line, as the cold front trudges eastward. We can't really call it a squall line because it will not be moving fast and it will be broader than a squall line. Strong-to-severe segments are expected along the line, with large hail and damaging winds. Almost the entire line should be producing lots of cloud-to-ground lightning. And a fourth factor to the storm line: locally heavy rainfall with spot flash flooding are possible. Much of the line will be capable of heavy rainfall, even if it is not technically severe. Storms will push into East Texas during the evening hours.
Tuesday is a very interesting setup, because we've already seen it twice before this season. Storms fire to our west and hang back until the upper low moves eastward to bring the activity here. While there is no cap over most of North Texas, abundant clouds will help to combat instability by limiting daytime heating.
