Once again, spotty showers with some embedded heavier storms have occurred across the state today. Notice some locations received over an inch of rain in a short period of time while others missed out altogether or only had a light shower as shown on the statewide rainfall map, courtesy of the good folks at the OK Mesonet.
The same general pattern is also evident with the 7 day totals, again courtesy of the OK Mesonet.
The 14 day totals reflect the very heavy rains that occurred in some locations but again, those heavier rains were spotty. Rainfall has occurred at all locations, but many of us have only received relatively light amounts and as mentioned before, the month of May was actually a dry month not only for Tulsa, but statewide; at least, in comparison to what is considered normal.
I mention all that because the pattern is changing and the scattered daily showers we have had for the last several weeks will come to an end on Saturday. Look for a front to arrive during the morning or early afternoon hours which will be followed by northerly winds at the surface and aloft. That will bring much drier air over the state scouring out the moisture and producing clear overnight skies Saturday night and lots of sunshine for Sunday.
For tonight and into the day Saturday though, there will still be cloudy skies and chances of showers and some embedded storms. The front itself may set off a few storms by early afternoon before the skies clear behind the cool front later in the day. The chances of rain will be on the low side at 20-30% for the most part, but any storms will be capable of dropping locally heavy rains in a short period of time.
The moisture will also keep us warm tonight with overnight temperatures only falling into the mid-upper 60s along with high humidity levels. By Saturday afternoon, our skies will be clearing, temperatures will rise into the mid 80s, but the humidity will be dropping below the 50% level for the first time in a long time.
That will be followed by bright sunny skies for Sunday and much of next week but the northerly winds through Sunday will keep dry air in place allowing our nights to drop into the lower 60s if not some of the cooler valleys reaching the 50s by Sunday and Monday mornings.
By later in the week, a return to southerly winds will bring the dew point temperature back to around the 70 degree mark which means our nights will be much warmer with overnight lows only dropping to near 70 as you can see on our forecast page. Our days will also reflect the abundant sunshine with daytime highs expected to reach 90 for the first time this year. Those higher dew points will also push the heat index well into the 90s by late in the week.
By next weekend, those southerly winds will also bring a deeper layer of moisture this way so will introduce a slight chance of a shower or storm, but not the widespread, daily activity we have just experienced. In fact, as you can see on the 8-14 day outlook, the trend will be for temperatures to average above normal and precipitation to be closer to the seasonal norms for this time of year. By the way, the normal max/min for early June is 84/64 which rises to 88/68 by the middle of the month and 91/71 by the end of the month.
So, stay tuned and check back for updates.
