Weather Summary

Weather Underground midday recap for Saturday, May 25, 2013.

Heavy rain over Texas caused major flooding for San Antonio, while showers and thunderstorms turned severe over the Northern High Plains on Saturday. Onshore flow from the Gulf of Mexico for the southwest, in combination with a wave of low pressure that moved eastward over Texas, allowed for extremely heavy rainfall to develop across south-central Texas late Friday into Saturday. Rainfall totals at San Antonio Airport, Texas reached up to 9.87 inches by mid-day Saturday. This broke the record for the heaviest rainfall over one calendar day in May for San Antonio. The 24 hour total from this rainfall event has reached up to 12.16 inches, but did not break the record for the heaviest rainfall over a 24 hour period for San Antonio, which is 13.35 inches. This system created major flooding for San Antonio and the surrounding area.

In the North, a low pressure system moved off the Northern and Central Rockies and created a warm front that stretched from western Montana into the Upper and Mid-Mississippi River Valley. This system kicked up scattered showers and thunderstorms over western Montana and eastern North and South Dakotas, while more widespread rain showers developed over Illinois and Iowa. Some of these storms turned severe with large hail and strong winds. Pea to quarter size hail was reported at Belfield, North Dakota and Burns, Montana.

In the East, a low pressure system brought more rain to the Northeast. Precipitation from this system turned to snow overnight Friday and into Saturday morning due to cooler temperatures, but most places that saw snow, only a dusting of snow.
