Record Lows Tied & Broken – Gradual Warming Trend Begins
This morning was the coldest we’ve seen so far this season, with most communities cooling below freezing, thanks to high pressure overhead and a mainly calm wind overnight. Huntsville tied its morning low for the day of 28° (1942) and so did Decatur cooling to 27° (1962). Muscle Shoals was just one degree shy of their record low for the day of 28° (1962). Winchester, Tennessee broke it’s morning low record this morning of 29°, by cooling to 25°.
Most woke up to the first widespread frost of the season across the Tennessee Valley. There were also some areas of dense fog, mainly over/along the Tennessee River. Check out this shot of river fog from earlier this morning from our Jack’s camera in Guntersville.
High pressure has now shifted east of the Tennessee Valley and with abundant sunshine and a light southerly breeze, temperatures are warming up rapidly! As of 11:00 am, many are already in the low to mid 50s!
Expect high temperatures to range from the upper 50s, to low to mid 60s this afternoon. We will remain mostly sunny, with a few high clouds building in associated with a weak disturbance. Clouds will continue to increase this evening and overnight ahead of another disturbance, with a small chance for a sprinkle or two late tonight/early Sunday, but expecting our air mass to remain too dry for most/if any precipitation to reach the ground.
Due to the cloud cover and a light southerly breeze overnight, morning lows Sunday will average about 10-15° warmer than this morning, mainly in the low to mid 40s. Sunday will feature a partly to mostly cloudy sky, with highs even warmer, in the mid to upper 60s. Minimal rain chances exist through Wednesday, before our next significant storm systems moves through likely sometime on Thursday. This means it is looking like Halloween will be wet, but exact timing of the rain and thunderstorm potential still remains a question due to a few model discrepancies. As we progress through the next 36-48 hours, we’ll have a better idea of what to expect on Halloween. For now enjoy the nice weather!
