Our small hopes for snow Christmas Eve have disappeared completely as the wave we were tracking with this low potential for snow is expected to move farther away from Texoma.

However, there remains a chance of snow in the forecast…on Friday night, December 22.

Here’s the set-up: a strong cold front passing Thursday night is followed by an upper-level system moving overhead Friday. This pattern (given the expected temperatures) is favorable for a cold rain; amounts over an inch are possible.

The precipitation may change to wet snow underneath the core of the upper-level component Friday night, when the coldest air aloft is available for both lifting and cooling of the air mass. This feature (shown by the blue “X”) will be weakening as it passes, reducing the potential for a major snow event. STILL….

An inch or so of slushy snow will be possible along the track of this impulse; we’ll need to see exactly how this lines up before predicting a precise snow area (if any), but please know there’s a moderate potential for wet snow over PORTIONS of Texoma Friday night.

An update to this blog will be posted Thursday night after the evening models come in….around 9:30 pm.

Take Care,
