A dramatic pattern change shown in the graphic below allowed the really cold arctic air to our North to drop in closer to our area and bring some freezing overnight temperatures to us with the clear, cloudless skies. The dew point was very low at 24 degrees allowing us to fall to 26 degrees for a short period of time this morning. Don't put your sweaters and jackets away just yet. It's still January!!!
Still colder daytime temp today. It will be in the mid 50's today and close to freezing tonight at 35 degrees with no cloud cover to provide the blanket effect. Some folks in the low lying areas of SA County will see the lows fall to near or slightly below the freezing mark once again tonight. However, we will still see a warmer trend in our day and evening temperatures with all the clear skies allowing the sun to heat us up. This cold air will be carried by the upper jet stream rapidly to our East out of our area.
