A BACKDOOR COLD FRONT BRINGS COOLER WEATHER AND SOME FOG TO PARTS OF THE AREA WEDNESDAY MORNING… THE RAIN HAS BEEN DELAYED UNTIL FRIDAY, WHEN WE MAY SEE SOME HEAVY DOWNPOURS

The frontal system that was initially supposed to bring showers as early as today (Wednesday) has been continually slowing down as it makes its way eastward across the central states. Now, meteorologists are predicting that we won’t see rain until Thursday night and more likely on Friday. As deep moisture gets pulled northward from the Gulf of Mexico and Atlantic Ocean, some heavy rain may occur. The trough associated with the cold front is expected to become negatively tilted, which means that the trough axis will run northwest to southeast. This is significant since it results in the front moving very slowly and it usually results in very heavy rainfall for some locations… As far as our weather today is concerned, a backdoor cold front has brought down a marine air mass, which means that it will be cooler in Hampton Roads due to the onshore flow. (See my Weather Fact on Backdoor Cold Fronts). Areas inland should be warmer today. Fog has also been an issue this morning in some spots. There is a slight chance of a shower or storm today and tomorrow, but rain chances go up significantly Thursday night and Friday as the aforementioned cold front slowly approaches from the west. Please monitor the local media and National Weather Service for the latest updates as localized flooding may be possible. Severe weather may also be possible. Winds are also expected to increase on Friday. As it looks right now, the weekend looks good but if the system slows even more, Saturday’s forecast could change. Much cooler air is going to move into our region behind the frontal system this weekend, so our air conditioners will get a break. That’s it for now. Have great day!
