Weekend Weather Update

RPM Model Early Sunday Morning.png

A colder weather pattern settles in for the weekend and should stick around through next week. There continues to be a chance for a rain/snow chance tonight and early Sunday. A short event overall, but the below average temperatures should stick around for the long term through next week.


(IMAGE GALLERY ABOVE: #1 & #2.....SHOWING THE DIFFERENCE IN TRACK OF THE SYSTEM BETWEEN THE RPM MODEL AND NAM MODEL.......#3. SUNDAY MORNING TEMPERATURES........#4. SUNDAY AFTERNOON TEMPERATURES)

CLOUDS & COLDER SATURDAY

The 70s from the past week will all be a memory as colder air moves in today. Clouds also moving in as well. Some periods of light rain at times, and even a mix along the Cumberland Plateau. But, any amounts look light during the day. Otherwise, a cloudy sky and afternoon temperatures only reaching the upper 40s. A steady breeze from the north at 10 mph.

WINTRY CHANCE TONINGT - SUNDAY MORNING

There continues to be the chance for some wintry weather for a period of time overnight tonight and into Sunday Morning. The question though is how much. Forecast model data has been up and down with moisture amounts and a few models show a possible shift south. But, we'll have to watch those trends into Saturday as the system develops. A chilly rain Saturday Evening, could give way to a rain/snow/sleet mix as colder air arrives aloft. Through the overnight hours this could transition to periods of snow showers through sunrise Sunday. It appears that any wintry precipitation remaining Sunday Morning quickly ends to the east. By afternoon, sunshine returns and temperatures jump back into the 40s to near 50.

The warm ground from the Spring warmth lately should be a limiting factor for any accumulation. And, temperatures by Sunday Morning could still be above freezing in the city, but below freezing higher elevations. This is why the higher elevations remain the favored area for a possible inch or two. Local roads mainly wet (slushy) in the areas that have snowfall. But, higher elevations could be slippery because of below freezing temperatures. Around the city mainly an inch or less. Again, this will all depend on the track of the low pressure system along the Gulf coast battling colder drier air moving in locally.

Again, anything that does accumulate should be short lived as temperatures rise quickly into the 40s by the afternoon.

EVEN COLDER NEXT WEEK

The weekend chill is just the start of a length cold spell. Mid 30s Monday Morning, then highs by the afternoon near 50. However, another approaching cold front brings some rain Monday Afternoon and Evening. As colder air spills in behind that front, the rain could end as a wintry mix into the predawn hours of Tuesday, especially north and east. Tuesday looks windy and chilly with afternoon highs only in the mid/upper 40s and even some flurries at times.

Even colder air gets pulled south on Wednesday which could lower our high temperatures to only the lower 40s by afternoon. A Hard Freeze could occur Wednesday Night and Thursday Morning with temperatures dropping into the mid 20s. Dry through late week with highs warming back to near 50 Thursday and upper 50s Friday. But, freezing temperatures possible both mornings.

As always you can depend on the StormTrack 9 Team for updates!
