Update on Monday storm

ATLANTIC PROVINCES STORM MOVG INTO ATLC EARLY IN PD AND NEXT SYSTEM DEPENING OFF CAPE COD.. MDL HAD A GOOD HANDLE ON THAT FIRST SYSTEM AND IS EXPECTED TO CONTINUE AS SHOWN BY LATEST 06H QPF VERIF VLD 18Z. COLD AIR INVADING THE GULF OF ST LAWRENCE LIKELY TO GIVE SNOWSQUALLS OVR PRONED AREAS. WRF-NAM IS AN OUTLIER WITH NEXT SYSTEM DEVELOPING OFF ERN SEABORD BEING TOO SLOW. POSITION WISE GEM REG, GLB AND ECMWF ARE IN GOOD AGREEMENT WITH LOW S OF CAPE COD BY 48H. UKMET IS A BIT FARTHER EAST. GEM REG IS THE MOST INTENSE WITH THAT SYSTEM WITH LOW AT 1001MB BY 48H. GLB AT 1005 MB AND GFS NAM AND ECMWF AT 1008 MB ARE WEAKER. THERE ARE POTENTIAL FOR DEVELOPMENT WITH NEGATIVELY TILTED UPR TROF AND CAA BUT GEM REG COULD BE IN THE DEEP SIDE WRT INTENSITY. DIONYSOS SHOWING A LOT OF LATENTE HEAT RELEASE BY END OF PD WITH THAT SYSTEM AND GEM REG COULB BE A CARRY AWAY WITH DEVELOPMENT. WILL GO MORE WITH CONSENSUS AROUND 1005-1008 MB ATM. POSITIONWISE THO GEM REG LOOKS REASONABLE. STAY TUNED FOR TONIGHT FCST.

Weekend System update

At 12z the models were showing the low to be in or near the Bay of Fundy Saturday morning, giving NB snow and freezing rain as the temperature falls.


A look at the models from 12z today for Tuesday 00z.

The GFS GEM GLB and the EURO all show the system off NS to be out to sea a good distance. They will have to bring system closer to sure for us to get a storm out of this.

Something To WatchUpdated: Thursday, November 30, 2006 4:03 PM
The major storm currently over the Central states is getting most of our attention right now, but here is something to watch for. The cold front trailing the storm will stall along the Southeast coast this weekend where a second storm will begin to take shape Sunday night. The path it will take on Monday is very uncertain so, instead of an exact track, we have shown a window of movement. If this disturbance comes up the coast, it will snow in New England. A track more toward the east will result in little or nothing. More on this event will follow.

Weekend weather outlook and possible storm for late Monday

Today's runs of the models are similar to yesterdays so I am still going with some snow with western NB. As for NS rain with posible icing as temperature drops during the day Saturday.

The 12z run of the GFS and GEM GLB show a coastal storm off NS late Monday early Tuesday. The EURO shows the storm as well but far enough off the coast as not to have much of an effect on us. As of now looks like snow and strong winds.

A sunny but cool day today, with high temp recorded at 12:00 am. A bit warmer tomorrow then a warm front comes through on Thursday giving above average temperatures for Thursday and Friday with rain before a cold front pushes through some time on Saturday.

Looking at the runs of the GFS, Euro and GEM GLB from 12z Tues for 12z Sat, we see that the Euro and Can have moved further east, while the GFS has moved slightly east. If this continues there is a good chance of seeing snow in Western NB on Saturday. NWS in Maine has a good chance of snow in central and northern parts of the state.

Here is the GEM GLB, issued today at 12z for Saturday at 12z. Yesterday it wasn't showing up. Same are as EURO maybe a bit further east.



Here is the EURO issued at 12z today for Saturday at 12z. It has slowed down and moved to the west since yesterday.

Click on block to view

The GFS 12z for 12z Saturday is quicker and further east than the GBL GEM and the EURO giving a chance of snow for western NB. This may have to be considered an outlier, but has remained consistant to last nights run, something the two other models haven't done.

Sunday, November 26, 2006


Here is the Euro issued today at 12z for 12z next Saturday. It has the low further east than the GFS, still giving NS rain But western NB snow. Interestingly the Canadian Global shows no low at all.
