Things appear on track at this point. A weak boundary is moving southward this morning and will bring gusty north winds and slightly cooler air to the region today. Afternoon highs yesterday ranged from the lower 70s across far eastern OK to near 80 across the central and western part of the state. Record highs were set in a few locations yesterday, just a week following bone chilling record lows. High temperatures today will be in the mid to upper 60s with mostly sunny conditions after morning clouds. A slight chance of a rouge shower is possible across far eastern OK before the cold front sweeps south of the area this morning.
The front will stall to our south tonight and move northward tomorrow as a warm front. This will bring moisture back over the region with a chance of some light showers Saturday along with gusty south winds. Afternoon highs are expected in the lower 70s.
A stronger system will be approaching Sunday evening into Monday morning. This will bring a chance of scattered showers and storms to the area along with colder air Monday and Tuesday. Afternoon highs will be in the 40s with morning lows in the upper 20s or lower 30s.
The air mass will modify Wednesday and Thursday with more seasonal type air, but the cold air will move back into the region by the end of next week. There will be a chance of some precipitation with this system with some colder air present. We'll be watching this time period closely.
I have added a chance of showers and storms to the Thursday period before the colder air moves into the region either Thursday late or Friday of next week.
I am fascinated by the geophysical sciences, and this includes earthquakes. I closely monitor USGS earthquake reports and have noticed a large increase of minor earthquakes in central Arkansas during the past week. This area has been experiencing a large number of minor tremblers for the past year or so, but the activity had diminished prior to the past week. If my eyesight is not failing me, I count 18 reports of minor earthquakes in central Arkansas during the past 3 days.
