Fortunately, the rains last night and this morning were fairly generous for some locations, although many of us could still use a good soaking rain. The map on the right from the OK Mesonet shows the total rainfall over the last 24 hours and some of the drought stricken areas in particular received some good rains for the first time in quite awhile. There remain some boundaries left over in the surface wind field from those overnight and early morning storms which could lead to a few storms re firing late this afternoon. If so, these would most likely occur in the extreme N and NE counties of the state and will quickly move away or dissipate after dark.

This rainfall footprint will also have an impact on temperatures for Monday and perhaps Tuesday. A brisk S to SW wind will return for both days and with plenty of sunshine that would have the potential for triple digit temperatures. However, the evapo-transpiration from the recent rainfall has a cooling effect which should mitigate that somewhat and at least for now I am holding us into the mid-upper 90s both days. A normal daytime high for this time of year is in the upper 80s so we will still be about 10 degrees warmer than normal.

Another weak cool front still is on schedule to arrive Tuesday evening or night and will bring with it at least a slight chance of a shower or storm. For now, it appears that the convergence along the boundary will be minimal and the moisture availability will also be somewhat limited so it does not presently look like a significant rainmaker. That is why the rain chances are held to around the 20-30% range for Tuesday night and Wednesday. The more NE winds behind the boundary on Wednesday should also provide at least a brief break from the excessive heat as well.

For the latter part of the week and going into the coming weekend, conditions aloft are somewhat supportive of a series of weak systems which could provide at least a slight chance of a shower or storm on any given day. At this time, a repeat of the Saturday night/Sunday morning system does not appear to be in the cards and we will have to settle for the popcorn type showers or storms which will still be capable of dropping some pretty good rainfall but only for very limited areas.

This also means temperatures will continue the trend of this entire month in which we will be well above normal both at night as well as during the day. So, stay cool, stay tuned, and check back for updates.
