A weak upper level wave is moving across Kansas into Missouri this morning on the northern periphery of the mid level ridge position to our southwest. It's possible a few scattered to isolated showers or storms will be possible across the area for a few hours this morning. Most of these would be across extreme northeastern OK.
Later today a few isolated storms are possible across the area as afternoon temps move into the 100's and a weak boundary approaches northern OK. A weak upper level disturbance may also move out of north Texas into southeastern OK and may provide a few more storms across southern OK. Any mature storms could produce damaging downburst of wind.
The temperature will along and ahead of this weak frontal boundary. The southwest surface wind combined with compressional warming of the air mass will lead to the hottest readings of the week. The weak boundary will slide southward Thursday. The boundary is expected to stall around the I-40 area and therefore the southern half of the state will see very little temperature change from the previous few days.
Temperatures may warm back up Friday and Saturday before another "more robust front" will arrive Monday bringing temperatures down into upper 80s along with some pleasant morning lows.
The system continues to basically be on track for a jog up the east coast. This means the system will stay east of Florida and could brush the outer banks of the Carolinas. As discussed here yesterday, the model data has continued to show a slight jog east from the previous day's tracks. This means this hurricane may move more northward as it brushed the Outer Banks of the Carolinas before making landfall somewhere as far north as New York.
The intensity forecast has not changed much and the geographically large hurricane should become a Cat 3 storm as it brushes the outer banks but would slowly weaken as it travels more northern latitude.
Several notable earthquakes occurred yesterday including a 5.9 magnitude quake near Charlottesville VA and a 4.6 quake in Colorado. The VA earthquake was the largest earthquake in that region since May of 31, of 1897.
