Damp opening day with snowflakes? Hard freeze possible

Many plants have emerged or are emerging from their winter slumber.  While many of our plants are well equipped to tolerate late freezes, some do so better than others.  Since forewarned is forearmed, you may be interested in the following forecast.

Opening day snowflakes are possible with a very cold air mass early next week.  Night-time temperatures may fall into the mid-20’s as well.

From the National Weather Service forecast discussion:

AN UNSEASONABLY COLD AIRMASS WILL THEN FILTER INTO THE REGION BEHIND
THE FRONT AS MID/UPPER LEVEL LOW ROTATES SLOWLY EAST ACROSS THE
GREAT LAKES THROUGH TUESDAY. THIS WILL LEAD TO SCATTERED SHOWERS
MONDAY INTO TUESDAY AND GIVEN FAIRLY COLD LOW LEVELS…WILL LIKELY
SEE ANY PCPN AT LEAST MIX WITH SOME SNOW SHOWERS AT TIMES. DRY
CONDITIONS AND MORE SEASONABLE TEMPERATURES WILL THEN RETURN BY
WEDNESDAY AS HIGH PRESSURE BUILDS BACK INTO THE REGION.

Abnormally dry conditions re-establishing

This week’s US Drought Monitor shows abnormally dry conditions re-establishing in the Ohio valley, especially in southern Ohio and northeast Kentucky.  Drought lingered in these areas through the end of 2008.  While a couple good winter storms eased the drought, these areas never got regular, deep rainfalls.  Rainfall at my Cheviot 0.9SSE location has been under 2 inches per month in February and March.    It has been uncanny how ALL recent storms have failed to produce more than a quarter of an inch of rainfall.  As temperatures warm, the rainfall deficit will become more apparent and significant unless we can start to get some rainfall.
