Today’s Forecast Update
Well, I’m nothing for drawing…but here’s something pretty impressive. Look at the dewpoints (the bottom number in each stacked pair) east of the line I drew and west of the line. Our dryline is setting up, nice and clear, right along US 83.
Meanwhile, mid-50′s dewpoints are now to OKC, in a narrow tongue along I-35. Visible satellite shows moisture streaming N.
The clouds overhead (and to our south) are showing the moisture streaming in. Take a look at the herringbone patterns in two locations….the lower clouds in SE Oklahoma, which show the southerly surface-level winds, and the higher clouds in Central KS, which show the WSW upper-level winds.
The edge of the clearing is not far to our west — just west of Pratt, at the moment. Remains to be seen how long it will take for that to erode and give us some additional instability.
