FORECAST IN DETAIL

Yesterday may have qualified as the nicest day of this week. While we still expect to see sunshine today and at times tomorrow, temperatures will be cooling down to more seasonal levels due to a wind change (now arriving from the north and east). A disturbance may introduce showers on Thursday and now there is a possible wrinkle for this coming weekend. A combination of coastal low pressure and more onshore flow could trigger clouds and showers; but our confidence is definitely still low at this early stage.

Today (Tuesday): Winds from the east and northeast usually introduces more opportunities for cloud cover over the area compared to yesterday along with the cooler temperatures. Look for partly sunny skies and highs in the mid-to-upper 50s. Confidence: Medium-High

Tonight: Expect partly cloudy skies with temperatures again dropping down into the 38-44 (suburbs-city). Confidence: Medium-High

Keep reading for the forecast through the weekend...

Tomorrow (Wednesday): A combination of the easterly flow and a disturbance passing mainly to the west of the area means that the cloudy periods may outnumber the sunny ones tomorrow. It appears as though the chance of showers will hold off until late tomorrow night or into Thursday. Temperatures should still be on the seasonally cool side with 50s throughout the area. Confidence: Medium

Tomorrow Night: Mostly cloudy with a 30% chance of late night showers. Look for low temperatures again in the mid-to-upper 40s. Confidence: Low-Medium

A LOOK AHEAD

Thursday looks mostly cloudy right now with a 40% chance of showers. Highs should again be stalled in the 50s. More clouds are expected Thursday night with a 40% chance of more showers and lows in the mid-to-upper 40s. Confidence: Low-Medium

Showers (30% chance) and clouds may linger through the first half of Friday with the possibility of some clearing in the afternoon. Highs should be in the mid-to-upper 50s once again. That pesky wind from the east may also persist. Confidence: Low

Unsettled weather may re-assert itself over the weekend , particularly the second half. There is even the threat of coastal system approaching the region. After a sunny start, we are cautiously introducing clouds late Saturday with highs in the upper 50s to near 60. Sunday looks mostly cloudy with a chance of rain (40% right now). Confidence is particularly low on the weekend outlook currently, so check back to this site for updates over the next few days. Confidence: Low

CWG,
pardon me, totally personal and off-topic...but...

could you point me to a forcast for the puerto rico/turks & caicos area for next week (nov 22-28)? any storms coming down there?

thanks. THINK SNOW!

Yes Matt, yesterday qualifies as the nicest day of the week and in fact, a rather rare day weatherwise for mid November.

We are back in the soup today and most of the remainder of this week with a moist southeasterly flow providing mostly cloudy skies with periods of rain mid and late week. Many areas should receive a half inch or more Wed. - Fri.

Overcast and calm with 47 degrees in the Valley at 9:45.

Yes, AugustaJim, it seems as though we keep finding ourselves back into the onshore flow this November...bad news for coastal beach erosion issues too.

Walter, there is a NOAA website for Puerto Rico. You can google it or find it here: http://www.srh.weather.gov/sju/

thanks,

Matt
