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.

Flash Flood Watch
Mobile & Email Alerts Statement as of 2:52 PM AST on May 25, 2013

... Flash Flood Watch now in effect through Sunday afternoon...

The Flash Flood Watch is now in effect for

* portions of Puerto Rico and Virgin Islands... including the
following areas... in Puerto Rico... central interior... Culebra...
eastern interior... Mayaguez and vicinity... north Central...
Northeast... northwest... Ponce and vicinity... San Juan and
vicinity... southeast... southwest... Vieques and western interior.
In Virgin Islands... St Croix and St. Thomas/St. John/adjacent
islands.

* Through Sunday afternoon

* showers and thunderstorms this afternoon and early evening will
pose a risk of localized heavy rainfall and isolated flash
flooding. Deeper moisture is being drawn over the area on east
southeast low level winds and will continue to interact with an
upper level trough approaching from the west. Widespread areas
of one to three inches of rain appear likely across central...
northern... and eastern Puerto Rico... with one to two inches
possible over Culebra and Vieques and the U.S. Virgin Islands.
These amounts of rain could fall in a short period of time
leading to flash flooding of small streams and rivers. The
current and expected atmospheric conditions are conducive for
showers and thunderstorm development again on Sunday across the
local islands. Given soil saturation and the amounts of rain
expected this afternoon and evening... any significant rain on
Sunday will cause additional flooding.

* Expect rapid rises in small streams or guts and rivers... with
mudslides possible in steep terrain.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions are favorable for heavy
rain across the watch area... which may lead to flooding. If you are
in the watch area... check your preparedness requirements...
especially if you have interests along area rivers. Keep informed...
and be ready for quick action if flooding is observed or if a Flash
Flood Warning is issued.

People in the watch area should continue to be aware of the
possibility for heavy rainfall. Avoid low lying areas... and be
careful when approaching Highway dips and underpasses. The heavy
rain could also cause mudslides in areas of steep terrain.

Stay tuned to NOAA Weather Radio... local TV... radio or your cable
television provider for later statements and possible warnings.
