Here is the latest drought monitor (released 12/07/2017) for areas that are serviced by the National Weather Service in Fort Worth. With below normal rainfall, drought conditions have worsened across North and Central TX over the past couple of weeks. Some parts of the area have worsened to attain D2 or Severe drought status. Little to no rain is expected over the next 3 to 5 days. As a result, there may be some fire weather concerns that crop up over the next several days.
Did you know that the shortest day of the year is just a few days away? On that day, we (North & Central TX) will have approximately 10 hours of daylight. This is around 4 hours less daylight than on June Solstice. The Winter Solstice (when we start the astronomical winter) will be on Thursday December 21st, 2017.
