Trending Unsettled
An area of high pressure over the Southern Appalachians will keep our weather dry today, but will be unable to hold on through the weekend.
Clear skies built into our area overnight and will be present through the morning hours. Eventually, small fair weather clouds will start to develop with a mix of sun and clouds through the afternoon.
Northwest winds will be in place throughout the daytime hours as well, with speeds just over 10 mph and gusts just under 30 mph.
The wind will keep temperatures a touch below the seasonal averages, with highs in the upper 60s and low 70s. As usual, the higher elevations will be cooler, while the warmest temperatures will be found in urban settings and in the general I-90 corridor.
This evening, a deck of thin clouds will build in from the south as winds turn southwesterly. These should pass through the area without any activity, departing early Saturday morning. Overnight temperatures will dip into the low 50s.
Fair weather clouds will again develop Saturday morning, but this time will build into afternoon showers and thunderstorms as an impulse of atmospheric energy passes through. A few isolated showers will be possible as early as Noon or 1 PM, but most of the activity should develop between 3-7 PM.
Not everyone will see rain tomorrow, and most of the shower activity should be brief. Some areas could see multiple showers, though. Thunderstorm activity should be limited to a few occasional rumbles of thunder.
Temperatures on Saturday will top out mainly in the low 70s. Winds will remain light from the southwest with speeds around 5 mph.
Stormy Weather
Sunday will be an active day as not one, but two more waves of atmospheric energy move through.
After a quiet Saturday night, showers and a few rumbles of thunder will move back in Sunday morning. This rain will be more widespread but should mostly last just an hour or two as it moves from west to east, exiting the area during the midday.
Some sunshine may work out behind this, with additional scattered showers and storms in the afternoon and a better chance for widespread precipitation during the late afternoon and evening.
There is still a high degree of uncertainty about how Sunday afternoon will unfold. If there is an opportunity for an unstable atmosphere to develop to fuel thunderstorm growth, there will be plenty of wind energy in the atmosphere to organize and strengthen the thunderstorms.
This will be something to monitor over the next 48 hours, and I will have updates this weekend as necessary.
A final piece of energy will pass through early Monday morning with a few stray showers. These should end by noon, leaving a mix of sun and clouds for the afternoon. Tuesday will also remain quiet with sun and clouds.
High temperatures both Monday and Tuesday will be in the mid 70s. Meanwhile, to our west, a massive dome of hot air will build across the middle of the nation. Temperatures in the 90s and 100s will be widespread from Texas to the Carolinas and north towards Michigan and Minnesota.
This heat dome is not expected to make it into the northeastern United States. Instead, being on the edge of the dome will make us susceptible to rounds of thunderstorms towards the middle and end of next week.
Again, there is a high degree of uncertainty in how this pattern unfolds and it is impossible to pinpoint when rain will be most likely late next week this far in advance.
