AWIS Weather Advisory: Rain and Frost Risk for Mid-Atlantic, Virginia and Parts of NC
in collaboration with AWIS Weather Services
Dear all,
Upcoming rain and increased frost risks especially in Western and Northern NC, Virginia and Mid-Atlantic will put us again in a difficult position, especially if row-covers are used for frost protection. Minimum air temperatures can fall below 40s in most of those areas. Predicted dew points are low and we expect mostly cloudless conditions on two consecutive nights: from Wed to Thu and Thu to Friday. There should be about half a day to let row covers dry after the rain today and tomorrow and the nights with highest frost risks (Wed-Thu, Thu-Fri). It is important to watch your local weather closely, especially if you are in Western or Northern NC, Virginia or the Mid-Atlantic.General Discussion
*** Some Frost Risk Northern Areas Thur/Fri Mornings*** Cooler Mid-Late Week
*** Warmer This Weekend Into Next Week
*** Few Showers, Isolated Storms Later Tuesday
*** Dry Wednesday-Early Weekend, Showers By Early Next Week
*** Perhaps Much Cooler Again ~ May 7-8, Northern Areas
The first two days of this week were likely the warmest
over the next 7-10 days.
An upper level disturbance and cold front will then move through
all areas on Tuesday. Some showers and isolated storms can be
expected ahead of the front. Most rain totals will not be that
heavy, averaging 1/2 inch or less, perhaps isolated heavier totals
mainly Eastern Carolinas and Virginia.
It will turn colder behind the front for the middle and end of
this week.
Arctic surface high pressure behind this front is further to
the North, moving from Central Canada early this week, SE through
the Upper Great Lakes at mid week and into the NE States late
this week. This will keep the coldest air further North than the
last couple cold events.
However, the potential is there for scattered frost by Thursday
morning. Highest risk will be inland areas of the Mid-Atlantic,
including Virginia, but could extend into Northern areas of
North Carolina as well.
Likely not quite as chilly Friday morning, but some patchy
frost may still be possible over the most Northern areas.
Growers, particularly over the Northern areas, need to monitor
the latest forecasts and be prepared for some protective measures
if needed.
It will turn warmer again starting Friday afternoon, into early
next week.
The next chances for showers after Tuesday evening will be late
this weekend, more likely early next week.
