DISCUSSION
RAIN AND SNOW ARE FALLING THIS MORNING. RIGHT NOW,
A LINE OF SHOWERS IS PRESENT ALONG THE CASCADES WITH SHOWERS
FOLLOWING WEST. AROUND 11 PM THERE WAS A STRIKE OFF OF THE COOS
COUNTY COAST, AND THERE IS A 15-20% CHANCE FOR LIGHTNING THROUGH
THE COOS AND CURRY COUNTY COASTS THROUGH 5 AM.
ON THE SNOW SIDE, SNOW LEVELS ARE AT 5,000'-5,500', AND SNOW IS
FALLING IN THE CASCADES. CAMERAS ARE SHOWING WET ROADS NEAR THE
CASCADES. ALTHOUGH ROADS WILL REMAIN ABOVE FREEZING TONIGHT, STILL
USE CAUTION WHILE DRIVING ALONG THE CASCADES AND EAST. SNOWFALL
TOTALS ARE FORECAST TO REACH 2"-5" FROM YESTERDAY EVENING THROUGH
THIS AFTERNOON. THAT IS NOT ENOUGH TO ISSUE ANY WINTER WEATHER
ADVISORIES. HOWEVER, IF THIS BAND OF PRECIPITATION REMAINS OVER
THE CASCADES FOR TOO LONG, THERE COULD BE A NEED TO ISSUE AN
ADVISORY IF TOO MUCH COMES DOWN AT ONCE. THIS WILL BE MONITORED
THIS MORNING.
SHOWERS WILL CONTINUE THROUGH THE MORNING AND INTO THE AFTERNOON.
THIS MORNING WILL HAVE THE MOST WIDESPREAD ACTIVITY WITH MORE
SCATTERED SHOWERS IN THE AFTERNOON. AS THE LOW SWINGS SOUTHWARD,
SHOWERS WILL BEGIN TO HAVE A MORE SOUTH TO NORTH MOVEMENT IN THE
AFTERNOON AS THE SHOWERS WRAP AROUND THE LOW. BETWEEN 5 AM AND THIS
AFTERNOON, WEST SIDE LOCATIONS COULD SEE 0.20"-0.50", WITH THE
HEAVIEST IN SOUTHERN AND WESTERN SISKIYOU COUNTY. THERE IS A 5-15%
CHANCE FOR LIGHTNING IN THE SOUTHERN OREGON CASCADES, EAST AND IN
NORTHERN CALIFORNIA THROUGH 5 PM.
TEMPERATURES WILL BE SLIGHTLY WARMER THAN YESTERDAY, BUT THEY WILL
STILL BE 5 TO 15 DEGREES BELOW NORMAL. NORTHEAST TO EAST WINDS WILL
BE ELEVATED THIS AFTERNOON INTO THE OVERNIGHT HOURS ALONG THE
RIDGELINES OF THE CASCADES. OTHERWISE, TYPICAL WINDS WILL BE
PRESENT. THE NEXT SEVERAL DAYS WILL HAVE LOWS WEST IN THE 30S TO LOW
40S (NEAR 50 FROM PORT ORFORD SOUTH) AND UPPER 20S TO LOW 30S EAST.
TUESDAY WILL HAVE ANOTHER SLIGHT WARM UP WITH TEMPERATURES IN THE
60S WEST SIDE AND 50S EAST SIDE. TUESDAY'S TEMPERATURES WILL BE ON
AVERAGE WHAT'S AHEAD THROUGH FRIDAY.
DRIER CONDITIONS WILL BEGIN FOR AREAS WEST OF THE CASCADES MONDAY
AFTERNOON AND EVENING. LEFTOVER SHOWERS WILL BE POSSIBLE TUESDAY
MORNING/AFTERNOON AS THE LOW MOVES EASTWARD. NEW RAINFALL AMOUNTS
TUESDAY ARE EXPECTED TO BE LESS THAN A TENTH OF AN INCH IN MOST
SPOTS.
RIDGING BUILDS AT THE START OF THE WEEKEND AND NEAR TO SLIGHTLY
ABOVE NORMAL TEMPERATURES ARE FORECAST SATURDAY. ENJOY IT WHILE IT
LASTS BECAUSE THE NEXT DAY A TROUGH MOVES IN AND BRINGS RAIN CHANCES
WITH COOLER TEMPERATURES ONCE AGAIN. SNOW LEVELS DURING THAT TIME
ARE FORECAST TO FALL TO 5,000'-5,500' ONCE AGAIN. THERE IS AGREEMENT
THAT THE PRECIPITATION COULD CONTINUE THROUGH AT LEAST SUNDAY
AFTERNOON, BUT AFTER THAT THE MODELS DIFFER BECAUSE ONE SHOWS A
CLOSED LOW KEEPING ACTIVITY HERE WHILE THE OTHER MOVES THE UPPER
TROUGH EAST FASTER.
AVIATION...13/12Z TAFS
LOW PRESSURE IS MOVING SOUTHWARD ALONG THE
COAST TODAY. LOW VFR CEILINGS ARE PRESENT WITH PASSING RAIN AND SNOW
SHOWERS THIS MORNING, AND WILL HAVE MVFR CEILINGS IN THE TAFS FOR
NORTH BEND AND MEDFORD AS LOWER CLOUDS HAVE BEEN STARTING TO
DEVELOP. MVFR CEILINGS ARE ALREADY FOUND EAST OF THE CASCADES.
HIGHER TERRAIN OBSCURATIONS WILL BE PRESENT AS WELL. LOCAL IFR
CEILINGS AND/OR VISIBILITIES ARE POSSIBLE IN HEAVIER RAIN THROUGH
THIS MORNING. FREEZING LEVELS WILL BE PRETTY LOW FOR THIS TIME OF
YEAR, GENERALLY 4500-5500 FEET. THERE IS ALSO ABOUT A 10-20% RISK OF
THUNDERSTORMS OVER THE MARINE WATERS AND ALONG THE IMMEDIATE COAST
LATER THROUGH 5 AM. THE MAIN AXIS OF PRECIPITATION WILL SHIFT
SOUTHWARD INTO NORTHERN CALIFORNIA MONDAY, BUT SHOWERS CAN PERSIST
INTO THE AFTERNOON JUST ABOUT ANYWHERE BENEATH CYCLONIC FLOW ALOFT.
EAST WINDS WILL REMAIN SLIGHTLY ELEVATED TONIGHT ALONG THE CASCADES
AND EAST.
MARINE...UPDATED 230 AM PDT MONDAY, OCTOBER 13, 2025
STEEP
NORTHWEST SWELL WILL PERSIST THROUGH 5 AM. LOW PRESSURE IS MOVING IN
FROM THE NORTH AND WILL KEEP THE CHANCE FOR WIDESPREAD SHOWERS
THROUGH THIS EVENING. SEAS WILL BECOME MORE CHAOTIC TODAY INTO
TUESDAY AS STRONGER NORTH WINDS GENERATE STEEP WIND WAVES. THIS WILL
MAINTAIN STEEP TO VERY STEEP SEAS, HIGHEST OVER THE OUTER WATERS
THROUGH TUESDAY. LIGHTER WINDS AND LOWER SEAS SHOULD RETURN ON
WEDNESDAY INTO THURSDAY. -SPILDE
