As it stands today, this is the driest May since record keeping began 126 years ago. Tulsa has measured just over a half inch of rain this month (.69"). The driest May on record was 1897 when less than an inch of rain fell on the area (.80"). However, we're about to get a break from the string of dry days. An upper level low pressure system out west that brought heavy rain, hail and tornadoes to the Denver area will provide us with an increased chance for showers and storms the next eight days.
The rain comes at a good time, especially with the latest drought monitor showing severe to extreme drought conditions expanding along I-44 and in areas to the north. Plus, this spring is currently the second driest on record. So far in 2014, Tulsa has only picked up a little over 5.5" of precipitation, which is more than nine inches below normal.
So how much rain will we receive the next few days? Several days of scattered showers and storms could bring decent rainfall totals to Green Country. Some of the highest totals may be over the counties that need it the most along the Oklahoma/Kansas state line. Projected totals range from .5" south of I-40 while 1-2" or more could fall north of that area along I-44. While some models are showing more and others less, the bottom line is that some much-needed moisture is coming our way. While it doesn't look like this will be drought buster, we could certainly go from one extreme to another if drought turns into flooding. If you have outdoor plans this holiday weekend, be prepared for some occasional heavy rain.
