What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Boise, ID wrote its last area forecast discussion before this river flood warning went out at Jan 17, 10:45 AM MST, 2 hours 20 minutes earlier.

Area forecast discussion, Jan 17, 10:45 AM MST, 2 hours 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
1045 AM MST MON JAN 17 2011

.DISCUSSION...NO FLOOD HEADLINES ARE OUT. GAGED SMALL STREAMS AND
CREEKS ARE STILL RUNNING HIGH BUT HAVE CRESTED. ICE JAMMING IS
GIVING SOME FLUCTUATING OR UNREPRESENTATIVE READINGS PER GROUND
TRUTH. RIVERS AND STREAMS WILL RESPOND TO THE DRY WEATHER AND
BELOW FREEZING TEMPERATURES THE NEXT FEW NIGHTS BY CONTINUING TO A
SLOW FALL WITH A DIURNAL CYCLE. WINDS HAVE COME UP TO 10-15 MPH
EVEN IN SHELTERED OREGON LOWER TREASURE VALLEY SO MILD
TEMPERATURES WITH FILTERED SUNSHINE WILL MAKE IT MUCH WARMER THERE
THAN SINCE MID DECEMBER /42 ON THE 14TH/. WINDS ARE STILL EXPECTED
TO REACH ADVISORY CRITERIA THROUGH THE MAGIC VALLEY SO THE
ADVISORY WILL REMAIN IN PLACE...MOUNTAIN HOME EASTWARD WILL ALSO
NUDGE 30-40MPH WEST WINDS THIS AFTERNOON. FINALLY TODAY ISOLATED
TO WIDELY SCATTERED LIGHT RAIN AND SNOW SHOWERS WILL PERSIST FROM
LOWER CLOUDS IN THE WEST CENTRAL AND BOISE MOUNTAINS.

&&

.AVIATION...ANY IFR TODAY WILL BE LIMITED TO SW IDAHO MTNS IN THE
VICINITY OF WIDELY SCATTERED SNOW SHOWERS. LOWER VALLEYS ARE VFR
WITH SCATTERED CUMULUS AND GUSTY WINDS. STRONGEST WINDS ARE IN
SNAKE RIVER VALLEY EAST OF KMUO WITH GUSTS TO 35 KTS. VALLEYS WILL
SEE AREAS IFR IN FOG DEVELOP BY EARLY TUESDAY MORNING.

&&

.PREV DISCUSSION...
SHORT TERM...TODAY THROUGH TUESDAY...MAJOR PRECIPITATION EVENT HAS
ENDED OVER THE FORECAST AREA WITH CLEARING SKIES AND CONTINUED MILD
TEMPERATURES IN ITS WAKE. ABUNDANT LOW LEVEL MOISTURE HAS ALLOWED
AREAS OF FOG TO DEVELOP IN THE LOWER VALLEYS. EXPECT THE FOG TO LAST
ONLY A BRIEF PERIOD THIS MORNING WITH GUSTY WINDS MOVING INTO THE
REGION LATER THIS MORNING. THESE INCREASING SURFACE WINDS IN
RESPONSE TO A STRONG UPPER LEVEL JET MOVING SOUTHEAST WHICH WILL
ALLOW GOOD MIXING TO THE SURFACE. HIGH TEMPERATURES TODAY WILL BE A
CHALLENGE WITH THE MILD JANUARY AIR MASS STILL IN PLACE AND A LOT
MORE SUNSHINE AND WIND THAN SUNDAY...WHEN SOME AREAS REALIZED RECORD
HIGH TEMPS UNDER HEAVY CLOUD COVER AND WIDESPREAD RAIN. A DRY SLOT
WILL REMAIN OVER THE REGION FOR THE NEXT 24 HOURS AHEAD OF A SHORT
WAVE MOVING RAPIDLY SOUTHEAST FROM B.C. ON TUESDAY. THIS FEATURE
WILL SPREAD SLIGHTLY COLDER AIR INTO THE AREA AS THE UPPER FLOW
BUCKLES WHILE KEEPING THE HIGH AMPLITUDE UPPER RIDGE AXIS OVER THE
EASTERN PACIFIC. TUESDAY WILL START OFF WITH SOME SUNSHINE BUT
CLOUDS AND SHOWERS WILL OVERSPREAD THE AREA FROM NORTHWEST TO
SOUTHEAST BY AFTERNOON. TEMPERATURES TUESDAY WILL BE 4 TO 8 DEGREES
COOLER THAN MONDAY.

LONG TERM...TUESDAY NIGHT THROUGH MONDAY...EXCELLENT MODEL
AGREEMENT CONTINUES IN TRACKING THE TUESDAY AND TUESDAY NIGHT
SHORTWAVE THROUGH THE REGION. THE BEST CHANCE OF PRECIPITATION
REMAINS OVER THE SW IDAHO MTNS WHICH IS CLOSEST TO THE TRACK OF THE
CENTER OF CIRCULATION. QPF AMOUNTS ARE MUCH LIGHTER THIS TIME DUE TO
A DIFFERENT SOURCE REGION AND TRAJECTORY. AMOUNTS SHOULD BE ABOUT A
TENTH OF AN INCH OR LESS IN THE VALLEYS AND UP TO A QUARTER INCH IN
THE MTNS. TEMPERATURE STRUCTURE WITH THIS WAVE LOOKS A LITTLE
CHALLENGING FOR PRECIP TYPE WITH A RAIN SNOW MIX IN THE VALLEYS AND
SNOW IN THE MOUNTAINS. THE EVENT IN THE VALLEYS WEDNESDAY MORNING
MAY END UP WITH A BRIEF PERIOD OF SNOW DURING THE MORNING COMMUTE.
THE HIGH AMPLITUDE UPPER RIDGE THEN BUILDS ALONG THE WEST COAST WITH
A DRY AND COLDER REGIME FOR WEDNESDAY THROUGH FRIDAY WITH
TEMPERATURES NEAR SEASONAL VALUES. ANOTHER DISTURBANCE APPROACHES
THE REGION LATE FRIDAY NIGHT INTO THE WEEKEND FOR WHAT APPEARS TO BE
MORE UNSETTLED WEATHER WITH LIGHT AMOUNTS OF RAIN AND SNOW AND
SLIGHTLY ABOVE NORMAL TEMPERATURES. THE COLDEST AIR OVER NORTH
AMERICA CONTINUES TO SLIDE INTO THE NORTHERN PLAINS AND GREAT LAKES
DURING THE PERIOD.
