For the past few days, an upper-level ridge has been anchored over central North America, as illustrated below by the dynamic tropopause (jet-stream level) analysis for 1200 UTC (0600 MDT) 6 July analysis below.
That ridge, however, is progressing eastward and weakening, while a new ridge will develop over the western US. This new ridge will be centered over Utah by Wednesday afternoon.
At that time, 700-mb temperatures are forecast to be near 20ºC, about as high as they get in northern Utah.
As High as they get? Does this mean 107 is in the reach?
ReplyDeleteWhen we hit 107 on 13 Jul 2002, the 700 mb temperature was 20.2ºC. Right now, the forecasts aren't quite that warm, but we'll have to see how things come together over the next couple of days.
DeleteLooks like we will beat the average 0f 5 days @ 100+ this year with room to spare
