****EXCESSIVE HEAT WARNING****

Wednesday, July 18th, 2018 9:43am CST

The National Weather Service office in Fort Worth has already issued an Excessive Heat Watch beginning tomorrow. This will likely get upgraded this afternoon to an Excessive Heat Warning. This is a very rare issuance for our area. What an Excessive Heat Warning means is that ambient air temperature and/or heat index values are expected to approach 110°F or greater for at least 2 consecutive days. A Heat Advisory remains in effect for Today. This is a much more common heat headline issued for DFW. A Heat Advisory is issued when ambient air temperatures are expected to exceed 103°F and/or heat index values are expected to reach 105°F for at least 2 consecutive days. 110°F plus heat at DFW is extremely rare. In fact, it has only occurred 12 times in a 120 years of weather records. Our hottest temperature on record is 113°F which occurred on June 26th and 27th, 1980. The current heat wave is expected to become quite severe and last through at least Monday. There is hope of a significant pattern change next week, and may even involve a cold front and increased rain chances. However, the heat may get exacerbated by the cold front before any real relief arrives. Please take greater precautions if being outdoors as the stress of this magnitude of heat can really limit the body’s ability to effectively cool itself leading to heat related illnesses, including heat stroke.

SEVERE HEAT WAVE EXPECTED TO GRIP NORTH TEXAS THIS WEEK

Monday, July 16th, 2018 9:17am CST

A severe heat wave is expected to grip the region this week with some of the hottest temperatures recorded in several years. Models are forecasting actual ambient high temperatures to be between 105°F and 110°F as early as Tuesday and lasting through at least next Sunday. Fortunately, heat index values may stay close to the ambient temperatures, or in some cases, below the ambient air temperature as we are expecting dewpoints to mix out by the maximum heat of the day. All of this is because of a strengthening high pressure system over the four corers region that will be expanding eastward as the week progresses. We have also had very little rain and have a parched ground that will bake in this type of setup, actually exacerbating the heat wave. Heat Advisories will likely be posted by tomorrow and actual Excessive Heat Warning criteria may be met in some areas. Residents should be aware of the extremely hot conditions and limit outdoor activity as much as possible. If you do have to be outdoors, plan to take frequent breaks and keep hydrated. These types of extreme temperatures can lead to heat related illness quickly, and even, heat stroke. The body loses its ability to effectively keep cool when temperatures get this hot.

DFW OFFICIALLY HITS 100°F FOR THE FIRST TIME THIS SUMMER 2018 SEASON

Saturday, June 23rd, 2018 7:28am CST

Yesterday, June 22,  2018, the mercury officially hit 100°F at DFW Airport. This marks the first time of the summer 2018 season that the temperature hit the century mark. The last time DFW Airport hit 100°F was last August 19, 2017. This did not affect the record for the date which still remains as 103°F set in 1953. This is also a few weeks ahead of the average first 100 degree date, which typically occurs in mid-July. We average about sixteen 100 degree days per summer season.

BITTERLY COLD NEW YEAR’S FOR DFW

Thursday, December 28th, 2017 6:06pm CST

A major Arctic air outbreak is expected to affect the area over the New Year’s holiday. An Arctic cold front will push south across the area on Saturday. There could be quite the temperature gradient from north to south as the front traverses the region. As the cold air filters into the region, what moisture is available in the atmosphere (not much) will be squeezed out as cold air cannot hold moisture. This will likely materialize in pockets of very light rain or drizzle from Saturday into Sunday. As temperatures drop below freezing Saturday night and Sunday morning, the drizzle will begin freezing to surfaces, possibly becoming mixed with sleet and/or snow grains as the cold air deepens. This is not expected to be a significant ice event for the area, but Sunday could have some travel spots on roads, especially bridges and overpasses. People with plans on New Year’s Eve should stay alert to the changing forecast conditions.

The cold air will deepen dramatically on Sunday with drier air filtering in from north to south effectively ending all precipitation. Strong and gusty winds will help sublimate any ice accretion rather rapidly. The cold will become the main story for much of next week. Once we drop below freezing on Sunday, we are not expected to get above freezing until Wednesday. Residents need to prepare now for 48+ hours of potential subfreezing weather. Lows New Year’s morning will be in the teens with wind chills in the single digits. People with plans New Year’s night will want to dress for the cold conditions. Highs will be in the 20s New Year’s Day and low 30s on Tuesday (still below freezing). The cold is expected to keep temperatures well below normal into Friday of next week.
