Marathon Forecast For Sunday, Rain On Monday
Temperatures dropped to the mid-30's this morning. It stayed above freezing across the metro area, hovered in the freezing range and just below in the outlying areas. The last freeze occurred Feb. 12th when it got down to 25°, the 2nd coldest temperature of all winter at DFW. We do not have freezing temperatures in the forecast for the next 10 days, taking us into the first week of March. The average start of the growing season in the metro area is March 13th. It is possible that we could a jump start to the growing season by 30 days. The current forecast for March is for above normal temperatures.
A LITTLE WARMER TONIGHT, TOMORROW MORNING
We'll start the morning tomorrow around 40° with a brisk south wind at 10-15mph. This will produce a wind chill in the 30's for the 25,000 runners lined up to run the Cowtown Marathon starting at 7:00am. Temperatures will quickly rise to the mid-50's by 11am as these south winds start to gust in the 25mph range. The winds will stay gusty through the early afternoon. Dewpoints will be in the 40's by mid-morning because of the south winds, the RH for the first few hours of the race will be between 70% and 60% but I wouldn't consider this a factor considering the wind and temperatures.
INCREASING CLOUDS SUNDAY
Rain is on the way, the only clue we'll have to that tomorrow is cloud cover coming in from the south. We'll be mostly cloudy by end of day after a sunny start. Temperatures are going to peak in the upper 60's with dewpoints in the low 40's.
A COUPLE OF CLOUDS DAYS AND SOME RAIN
Monday is looking cloudy with a 30% chance of light rain. Temperatures for the day start around 50 degrees and top out in the low 60's.
Tuesday is another cloudy day with even better rain chances and windy conditions. There is a good chance of rain during the morning commute with a very mild morning low of 60°. I'll put some storms in the forecast for that day, there is a chance for some severe weather associated with a dry line in the afternoon. A cold front comes in at the close of the day. Highs will still reach into the low 70's (it'll get into the upper 70's if the skies clear just a little ahead of the dryline). The HPC keeps rainfall amounts rather light. We need about 3/4 of an inch of rain to get to "normal" for the month. On the left is Monday's rainfall total forecast (under .10"), on the right is Tuesday (around .20"). Storms mean isolated areas of much heavier rain:
MILD AND DRY REST OF THE WORK WEEK
Highs on Wednesday and Thursday will be in the 70 degree range. Another Cold front arrives on Friday, it'll be a cloudy day with a 20% rain chance. Highs on Friday and Saturday look to be in the mid-60's.
