The Sunday system is well east of the state this morning. We'll be tracking 3 more systems during the next 7 days that could have wintry weather impacts across the state including portions of northern OK. The first will arrive Tuesday, the second Thursday into Friday, and the third Saturday. Temperatures are expected to remain well below normal this week with frigid conditions for the middle of the week.
The next system will arrive late Tuesday morning across the southern plains and the state of Oklahoma. This is a strong storm system but the track of the storm in most model data would now lead to higher snowfall totals across the north central and northwestern OK region. Significant snow is likely to occur in portions of central and east central Kansas. We should see some light precipitation beginning pre-dawn Tuesday morning across eastern OK in the form of light freezing drizzle or light sleet. Some snow would be possible by midday, but mainly near and northwest of the I-44 corridor. This system may also be a fast moving storm. A dry slot will quickly form and could greatly limit the precipitation across southwestern and south-central OK Tuesday morning and spread into northeastern OK after the noon hour. The areas to the northwest of Tulsa may be included in a winter storm warning, but most of our area wills more than likely remain in a winter weather advisory for this Tuesday event.
Wednesday will feature very cold air with temps in the single digits to lower teens for lows and highs in the upper teens and lower 20s. We'll get a break Wednesday with no precipitation in the forecast.
The second wave will approach the state late Thursday morning or possibly early Friday morning. This wave will have plenty of cold air in place before the precipitation begins which means all snow across eastern OK. But the accumulation will remain light.
The third disturbance for this 7 day planner will arrive Friday night late into Saturday morning to midday across central and eastern OK. This disturbance will also have cold air in place meaning most if not all precipitation types would remain snow for northern OK and southern Kansas. This system may also have the potential for accumulating snow.
In summary, the pattern will remain active with several chances for additional wintry precipitation across the region for the next 7 days. Temperatures will remain well below the seasonal averages.
Afternoon highs will stay in the 30s today.
The official high in Tulsa yesterday was 29 recorded at 1:18am.
Snowfall was officially 2.7" for Tulsa.
The normal daily average high is 50 and the low is 29.
The daily records include a high of 79 from 1924 and a low of -6 from 2011.
You'll find me on Facebook and Twitter.
I'll be discussing the forecast on numerous Radio Oklahoma News Network affiliates across the state through the morning and noon hours.
Thanks for reading the Monday Morning Weather discussion and blog.
Have a safe day and super day.
