Forecasters predict Baltimore could see wintry precipitation Thursday and again Sunday as cold air returns following brief midweek warmup
Baltimore residents should prepare for fluctuating temperatures and two separate opportunities for winter weather as January settles into the region. Forecasters are tracking systems that could bring snow Thursday and again Sunday, bookending an unsettled weather pattern.
Thursday brings first snow possibility
The first weather-maker approaches midweek, bringing the more immediate threat of wintry precipitation. Wednesday will start as another mild day before conditions change as the system moves into the area. A few rain showers are possible Wednesday as the front approaches, but the real story develops Thursday when colder air takes control.
Meteorologists express high confidence that temperatures will drop significantly Thursday, with highs struggling to reach the low 40s and upper 30s. This temperature profile creates an environment where precipitation could fall as snow rather than rain. However, forecasters caution that confidence remains lower regarding the exact type of precipitation Baltimore will receive.
Current projections suggest Thursday will likely feature a mix of rain and snow showers rather than pure snow. The marginal temperatures mean the line between rain, mixed precipitation and snow will be delicate, shifting based on small changes in temperature and timing. Areas north and west of Baltimore may have better chances of seeing accumulating snow, while locations closer to the Chesapeake Bay could remain too warm for anything beyond wet snowflakes.
Sunday offers second winter weather opportunity
Even as the Thursday system exits, meteorologists are monitoring another potential for wintry weather arriving Sunday. Details remain less certain for this second chance given the extended timeframe, but the pattern suggests conditions could again support snow or mixed precipitation.
The Sunday system will depend heavily on how the Thursday weather-maker behaves. If Thursday’s cold air lingers longer than expected, Sunday could feature better conditions for snow. Conversely, if milder air rushes back in between systems, Sunday might trend more toward rain or a rain-snow mix similar to Thursday’s forecast.
Forecasters typically gain better clarity on these secondary systems as the first passes through and they can better assess the atmosphere’s setup. Baltimore residents who remember the unpredictable nature of January weather know that systems forecast days in advance often shift, intensify or weaken as they approach.
Week starts chilly before brief warmup
Monday morning brought the chill that will characterize much of the week, with feel-like temperatures making it seem even colder than the actual air temperature. High temperatures Monday will struggle to reach the lower 40s, keeping residents reaching for winter coats and layers as they start the work week.
Tuesday offers brief relief as temperatures rebound into the upper 40s, providing a taste of slightly milder conditions before the pattern turns active again. This one-day warmup represents a common January occurrence in Baltimore, where brief mild spells interrupt longer stretches of cold weather.
Wednesday continues the mild trend before the first weather system arrives, giving residents a final day of relatively comfortable temperatures before winter reasserts itself.
Temperature swings complicate snow forecasting
The fluctuating temperature pattern this week makes snow forecasting particularly challenging for meteorologists. Baltimore sits in a geographic location where winter storms often arrive with temperatures hovering near the critical 32-degree mark, the point where rain transitions to snow.
Small temperature changes of just a few degrees can mean the difference between several inches of accumulating snow and rain that produces no winter travel impacts. The Chesapeake Bay’s moderating influence on temperatures adds another layer of complexity, often keeping areas near the water slightly warmer than inland locations.
Thursday’s forecast currently shows temperatures in the low 40s and upper 30s, right in the zone where precipitation type becomes most difficult to predict. If the cold air arrives slightly earlier or proves more intense than expected, more snow becomes possible.
Monitoring changing forecasts remains critical
With two distinct chances for wintry weather and a week of temperature swings ahead, Baltimore residents should check updated forecasts regularly. Weather prediction models run multiple times daily, incorporating new atmospheric observations that can shift forecasts significantly.
The Thursday system will come into sharper focus as Wednesday approaches, with meteorologists able to provide more specific timing and precipitation type information. Similarly, the Sunday potential will become clearer once Thursday’s weather passes and forecasters can better assess the pattern setting up for the weekend.
January weather in Baltimore often features exactly this type of active pattern, where multiple systems pass through within a week and temperature fluctuations determine whether precipitation falls as rain or snow. The week ahead serves as a reminder that winter weather season continues through January and into February, with multiple opportunities for snow remaining possible.
