A weak clipper to bring light rain and snow Friday night Quick update this morning. I spent time with my youngest daughter last night, which was needed and appreciated, so I am a bit late out of the gate. The system passing through the Great Lakes loses some juice as it moves eastward. The thing with these fast-moving systems, which operate with a positive or neutral trough, is that there isn't much to them. The mountains and north may pick up an inch or two of snow, and for most of the rest of the region, less than ¼" of rainfall by daylight Saturday morning. On that note, the next system on the way Sunday into Monday works off a trough of a more neutral nature. The upside for precipitation is that since the trough runs deeper, the moisture feed is better. The general idea of ½-1" of liquid equivalent is the sketch on the cocktail napkin for now, but given its neutrality, it will be more likely to rain than snow. The cold air comes in from the backside as the trough becomes negative and the surface low intensifies, eventually hitting Newfoundland. This brings snow showers to the north and mountains as a participation trophy. Notice the trend? This is what we dealt with last winter, and it is also why we are currently dealing with the drought. We need negatively tilted troughs to bring precipitation makers here, period. It's frustrating. COASTAL FLOOD STATEMENT FOR THE SOUTHWEST and MIDCOAST shorelines as astronomical high tides peak. The forecast high water in Portland is 11.8', where the minor flood stage is at 12'. A bit of onshore wind is all it takes for minor flooding, which is all that would result from it. Seas are running 2-4', which may cause localized splash over, if at all. The mountains are making snow. |
