Coltsfoot ( Tussilago farfara ) In Bloom On March 27, 2017

Although April 15 to May 15 is typically the most explosive period within the mountains for spring rebirth, numerous species of flora and fauna are beginning to become more visible ( especially at lower-middle elevations ).

MIN temperatures dipped to 0 degrees on March 16, and into the 10s on March 23, in high valleys of the High Knob Massif where spring is typically slow to emerge.
Big Cherry Wetland Valley of High Knob Massif – March 22, 2017

Somewhat cooler air will be felt on northerly winds Tuesday into Wednesday before the next upward surge of wind and temperatures occur Thursday in advance of the next round of showers and thunderstorms to close out the week.

Following a break, another significant system is likely next week with more showers-storms.  A shot of colder air will be possible by the middle-end of next week ( typical for April ).
NWS Precipitation Analysis-Estimate Past 21 DAYS

Although the above NWS Precpitation Analysis-Estimate is too low for the High Knob Massif area, where up to 6.00″+ has fallen in March, the gradient is generally correct with portions of Dickenson County being smoky over the past weekend due to wild fires ( March precipitation totals of 3.00″ or less in places ).  So a wetter pattern is generally good news for the mountain area as a whole.
